InstallShield is a package commonly used by software developers to allow their products to be installed easily on their customers' PCs. This process runs in the background and checks for updates to InstallShield itself -- contrast to issch.exe, which is an update service that checks for changes to programs that were installed using InstallShieldhttp://www.neuber.com/taskmanager/process/isuspm.exe.html 

If you want a detailed security rating about your ISUSPM.exe (and all other running background processes) read the following user opinions, and download the free trial version of Security Task Manager.

Note: Any malware can be named anything - so you should check where the files of the running processes are located on your disk. If a "non-Microsoft" .exe file is located in the C:\Windows or C:\Windows\System32 folder, then there is a high risk for a virus, spyware, trojan or worm infection! Check it out!

rate1 InstallShield Update Service Scheduler. Automatically searches for and performs any updates to the software so you are always working with the most current version   Ozan
rate4 Occasionally connects to the internet for updates, does not really let you know what it is downloading, can be somewhat annoying. I am going to remove it.  
rate3 software updater  See also: Link   Leo Jr
rate3 Not a danger but takes up space you can get downloads manually.  
rate4 It "suddenly" appeared after Microsoft changed their updating process. It lists updates for several things I've already updated so I don't trust it.   Carl
rate3 Nusence file  
rate1 Installdshield Automatic Downloader, checks application installations which are made using the InstallShield software for updates.   Damien Jorgensen
rate2 downloader - activates occassionally to download updates - can't see its added value   james Mac
rate3 Its used to update software that uses installshield but is impossible to remove!!   K1t10
rate5 Not listed in add/remove programs, reinstalls itself   Bill
rate0 It seems to be a MACROVISION (M) update product. I don't have "M" on my START UP list nor in my ADD or REMOVE files. It bothers me that it comes on automatically at start up.   hw huyler
rate4 the service hangs more often then it runs correctly, I am going to disable it.   jeff huyler
rate1 It is part of Windows Defender - Beta2   webbcues
rate1 Installshield Update Services. It is kind of buggy, doesnt always recognize what you have installed. It doesnt get uninstalled when you uninstall the installshield product or a product that uses installshield update service technology. Use the link for the uninstaller   Salim
rate3 Has issue's with Roxio Media Creator 8 Suite. EVERY time system reboots it attempts to update, even if updates are current.   RHuskey
rate3 Installs without asking. Near useless, not necessary. NOTE: Users should also remove Install Driver Table Manager from XP Services list using MSCONFIG.   JoeR
rate3 If configured incorrectly, will function as a trojan horse. Made it difficult to unistall Vongo (preloaded by HP on notebooks)   Ted Volin
rate4 It's a third party process that just appears, without your permission, with no notice, and no uninstall. In my book it's dangerous   Ken
rate3 ISUSPM.exe installed on my computer with the Paperport program. If you run it and click on the menu to see what programs it is checking for (Advanced) then you will likely see the program it came with provided it came onto your computer legitimately. You can also disable it to run at start up from the menu.   steve blomme
rate1 Updater, Came with Dell Laptop for my version.   jtsm
rate4 It is horrible and locks up the internet connection.  
rate4 Update Manager /Windows Installer error msgs prevent boot completion and any other installs System hangs   Stephen LaFond - Another HP Support Victim
rate1 it isnt dangerous at all it is just a installshield update manager   ben petti
rate3 I see no adverse effects from blocking it's update.   WarGasm
rate3 This process appears when I installed "WinDVD - Trial version" on my machine, in the same time a "Program updates" icon in the Start menu / Programs   YaHa
rate3 Mine seems to have come with a Quick Time/iTunes update. It asked if I wanted automatic update checking. That must be what did it. Everytime I log in it tries to run, but tries to find a nonexistent ISUS.msi file. Only way to get rid of it is to force an End Task on the process from Windows Task Manager.   dp Bethesda
rate4 I had it combined with windvd8 and when i uninstall it that macrovision updater stays and i cannot get rid of it.   H
rate1 Often steals focus while at a critical point in an online game. Very annoying.   ScratchMonkey
rate1 it is used by a few programs to update themselves   K-red
rate4 My system has slowed to a crawl and I have determined it is this file. think I will delete as well.   brenda
rate3 must be deleted to remove Vongo from HP systems   grikdog
rate3 Process belongs to Macrovision, a company that is in the business of illegal copy prevention. Apparently it interpret a certain "digital pulse signal" that is included on some DVDs (and other media) as part of an 'anti-piracy' prevention initiative. Not necessary and weather disabled or enabled, doesn't seem to make ANY difference to PC operation in the slightest. (link to CNet article on the Microsoft/Macrovision agreement: tinyurl.com34mj39)  See also: Link   Kel
rate3 This program installed itself when I installed the Walmart Downloads Store in Windows Media Player. If is not necessary for programs like this to install themselves without our knowledge.   RickH
rate3 You can remove the InstallShield Update Manager (isuspm.exe and agent.exe) by downloading a utility from installshield's website.  See also: Link   Donald Kinstler
rate3 This is the background check application for the InstallShield Update Service. It polls the servers to check for updates to other installed applications that ship with ISUS as part of the install. Applications that use it install it silently without any warning to you, so that's why it seems to suddenly appear. It can be removed but only via a 100% manual process that requires first killing the ISUSPM.exe and AGENT.exe processes, then cleaning the registry and Program Files\Common Files\InstallShield\UpdateService folders.   Travis
rate3 macrovision corporation spyware   adminONE
rate4 Uses up a great deal of resources. Slows down the whole machine.   Tony R
rate3 just laggs my connection when i´m playing wow   mark
rate0 It is a highly intrussive resource eater that does not let you know what it is doing. Forget online gamming while this baby is running.   GUS
rate3 Is also installed w/Sonic RecordNow. If you use the uninstaller available on the internet, it will break RecordNow. Is really a nuisance. Even if you turn it off in control panels it will still come up occasionally. Am currently researching a way to disable it in the registry. If anyone already knows how to do this, please post.   Spike
rate4 Experiencing problem in ripping a song I looked for culprits. I found ISUSPM.exe was running and using a fluctuating and high level of the CPU - about 30%.   stephenp
rate1 Among the items that are installed: Update Manager (ISUSPM.exe) is an application  See also: Link   FRANCIS SURROCA
rate3 showed up out of the blue, always trying to update random different programs i use each time i turn on computer, doesn't seem dangerous, just annoying   true graves
rate1 Used to provide download services, but runs from startup and EATS CPU power, so I disabled it from Startup. It starts when necessary for downloads.  
rate1 Completly harmles i got it with game medieval total war anyway you can freely delete it and check for program updates manualy if necesery ;)  See also: Link   Jack Daniels
rate3 This excuse for software loaded itself with a legitimate product and provides no uninstall. It is a complete waste of time and is positively harmful in this instance where it has located itself on a workstation which is part of a 10,000+ international workstation network. It is just a valueless piece of annoying junk.   Roy V Wilkes
rate3 Stupid. Updated files we never use, slowed down the computer with a message we couldn't delete. Annoying, but can be configured not to update anything (including itself). Will continue to pop up.   Raelynn
rate4 My computer was running really slow, and agent.exe was using up most of my processing, and would restart if I ended it. ISUSPM was also running. When I ended ISUSPM, agent.exe also stopped and neither came back. Now my computer is fast again.   jason
rate4 Macrovision technology is to defeat copying, so while this is sold as an "updater" it most likely is part of a copy protection scheme to validate software and disable improper copies. Is uses system resources, and gets installed without your knowledge, so therefore I consider it dangerous   Rob R
rate4 Can be linked to and used to hijack the computer from other software. Removing this helped resolve problems with Vongo and other software that re-installs itself despite your wishes.   Shawn
rate0 Appeared on my system after install demo "clive barker's Jericho"   Jeanjean
rate3 You may be able to get a list of all programs on your system using ISUSPM services by going to macrovisions website and searching for "UpdateManager" (direct link below ).  See also: Link   Randall Goodwin
rate4 A number of "freeze" events since installed with a program update.   dick
rate3 It's annoying. It interacted with Photoshop CS3 and drove CPU usage to 100%, effectively disabling the computer. Had to use "End Process" from Task Manager to stop it. I finally disabled it in the Startup Menu   Capt_J
rate4 Program loaded after installing reconfiguring my lap top to the factory setting.   TERRY WATSON
rate4 My firewall showed ISUSPM.exe attempting to connect after I logged in to my financial institution. Could be coincidence, but that strikes me as suspicious.   Boyd Ramsay
rate0 Randomly appeared December 11th. Took up 100% CPU with 6 or 8 processes of it running. Installshield WAS running, so I doubt it's dangerous going by what these people have said.   Bob Heinbokel
rate0 It use's 80% of my CPU I hate it  
rate3 Dangerous or not, i dont like programs that just install them self out of the blue and reinstall if uninstalled!   The Dane
rate3 Noticed after installing Desktop software for Blackberry. It's part of the Roxio Crapware   Greg
rate3 Installed with Roxio Media Manager 9 that came with Blackberry Desktop Manager. No uninstaller supplied   coder79
rate4 was using 50 to 60% of processor time. A nuisance   Dave
rate0 Just had "isuspm.exe failed to initialize properly. It will be shut down" error. Hence my visit to this site. BTW, size of my file is 221184 bytes.   BrianR
rate3 Don't think it is dangerous, but I uninstalled the software that installed ISUSPM.exe and now I don't want something using 3-4Mb of my precious ram doing nothing.   Rod J
rate4 CLAIMS TO BE INSTALL SHIELD uPDATE - IS A MEMORY LEAKY PIECE OF CRAP THAT DOESN'T DO ANYTHING OF USE AND SUCKS UP MEMORY TO MAKE YOUR SYSTEM RUN BAD - SOMEONE SHOULD RE-WRITE - SOMEONE SHOULD OFFER WHAT IT'S UPDATING SO WE KNOW WHAT WE'RE LOOSING BY DELETING - I RENAMED FILE TO BREAK IT   DAVE
rate3 I wanted it to remove ISUSPM.exe error and it did not. I am still getting the annoying message.   L. Ketch
rate1 before delete istallation folder, kill issch process too.   Eric
rate0 Remove it. Tracking apps.  
rate3 safe to delete   isidro
rate3 InstallShield creates installation tools that thousands of software vendors use to distribute software to you, their customers. About 80% of the Windows installations built in the world are built with InstallShield software, so most of the applications you install on your home computer use an InstallShield product.  See also: Link   CraigP
rate5 It is a time comsuming malicious software with potential to be very dangerous. If I sent this in an email it would be concidered a virus and I would be subject to prosecution.   Glenn
rate5 The uninstaller doesn't seem to work on my computer. Software Manager won't show me the "settings" page. I deleted the system permissions to execute it, I hope that works...   Gambit
rate5 My version constantly opens Windows Installer in the middle of everything, forcing you to keep the Task Manager open to end the process. More annoying than anything threatening. Assuming it is actually malware, because it tries to open Corel Photo Album, and Dell Online Data Safe, and makes the computer behave in a way it is not supposed to.   John
rate5 Fairly certain that this program prevented me from opening any program via the Windows Data Execution Prevention.   Scott G
rate3 Serves a non-essential duty and is wasteful and annoying   Jim
rate0 It seems to own my computer. I am forced to share time with it as it slows down operations and when terminated in Task Manager it restarts in about 5 minutes. The fan kicks up and the watts used for ISUSPM ar not worth what ever it is trying to do.   Phil H
rate0 Tried to eliminate, but finally used RegCure, Manage Startup, ISUSPM Startup and disabled it.   Warren Crawford
rate3 It is a useless program which takes about 3-4 MBs of RAM   Crazykiller
rate5 Intrusive software. Does not inform you of its install as part of the installer for whatever it is packed with (in my case, Roxio Media Creator 9). No uninstaller provided. Slimey software that is developed and distributed by an organization that does not care about its end users. As it is an update manager, it is ironic that the software is designed in such a a way that prevents dilligent users from configuring their machines to their liking.   Ryan
rate1 Came with Blackberry Desktop Manager   Bill
rate0 It installs itself sneakily and can't be removed. I'd call it malware. All it does in my case is frequently try and check for updates _to itself_. That's the only thing it has listed as 'things to check for updates for', as I uninstalled the one other application it updated (mode setting utility for a monitor I no longer use). Very annoying.   pete
rate3 It is an ennoying executer, in fact, as others have confirmed above (thank you!), installed by the Blackberry desktop using the Roxio Media Manager. As the Blackberry desktop is a crap-interface, I must say I inherited this ennoying pop up with my Blackberry. The ISUSPM.EXE is trying to update the Roxia Media Manager but does not find the updates nor can it gather the info from my PC. A Nightmare. Is now searching for help tp uninstall nad in this process I came to this site. Regards  See also: Link   JSN
rate3 it goes as agent.exe in zone alarm. i've denied it permission. also found a 'diagnose connection problems' as a new add-on. don't know if it's macrovision, but i disabled.   chris healy
rate5 it slowed down my computer so much i couldnt do anything, i felt like i was using a 386 on a dial up connection. Goddamn thing! i had to search out all isuspm files and delete them. i think i am rid of it. I do have blackberry desktop but i really dont even know how or why it just appeared one day. Who ever designed this should rot in hell, i dont know how he sleeps at night.   F'in Victim

rate2 Lauer  
rate3 NOT essential for Windows, eats memory & CPU recources. May interact with other programs (My case it was Acrobat) The program itself ISUSPM.exe installed itself with Blackberry Desktop Manager as part of Roxio media crap as noted it is a Macrovision installshield update program and as you can see it's a big pain find to get rid of.   Ziggy
rate4 Associated with Epson printer update. esource hog that makes my computer run hotter. Disable it for normal operations.   Time_runner
rate4 It got loaded on XP Pro with Roxio crap & is a pain   Pat OBrien
rate1 This file coupled with agent.exe are part of Macrovision update software, now Flexera Software. It is essential to have these files so that windows will get history of windows updates AND updates of other programs automatically. That said, these files are a pain in the cpu, causing my CPU to run at 60-70%. When I need capacity, I disable only ISUSPM.exe by quitting the process in windows task manager XP. CPU utilization drops to less than 5%.   Tippy -- layman's experience-
rate0 Seems to be connected to Macrovision. I used Code Stuff Starter to delete it from the registry   Joe
rate0 Came with Quick Time - Blackberry Desktop Manager - Roxio  
rate3 it is a software updater for Roxio software like the cd burner that ships with HP laptops. There should be no reason for this to start automatic and do this as a hidden process..!   kai r schantz
rate5 A rather nasty addition I got off of an adult game. It was installed to C:\Program Files\Common Files\InstallShield\UpdateService\. When it was run, it would shut down a number of my startup processes (including drivers run by executables & my virus protections) and delete them as startup entries. It would also create a startup entry for itself after shutting down your defenses. The only way to get those startup entries back on the computer was to shutdown isuspm.exe, uninstall & reinstall each program.   WonderGamer
rate4 Nasty had it once long while got again   Bill Man
rate1 InstallShield Update manager. Came with Paperport. Caused CPU to go skyrocket.   lhuser
rate5 Blackberry installs it.. It's Roxio Media Mananger which manages Roxio Hard Drive Watcher 9. I went to C:\Windows\SysWOW64\ISUSPM.cpl and right clicked it, then deleted it. Wikipedia - Malware (also: scumware), short for malicious software, is software designed to secretly access a computer system without the owner's informed consent.   justinb6003
rate4 Comes with MINITAB, I really hate this program as it slows my PC after I try to place an USB disk, it slows it to the point that takes more than 10 minutes to load anything   a pissed user
rate4 Hangs up internet connection. When i ended this process the internet continued to work properly   DB
rate4 BS installed by paperport 12 - sucks proc power - but cant get rid of it because then paperport is re-launching install process   odm973
rate5 acts as adware, runs invisibly, cannot easily uninstall, contains serious security holes, does not ask permission before installing itself thus fills every definition of malware.   Jimmy Wales
rate4 installs with dragon naturally speaking and periodically interrupts you with 'special offers'   dragon user
rate0 This file was installed along with Acresso "Updater" when we installed nuance PDF reader. A dirty trick to install crap like this without allowing end-users to opt out. I hear it trying to "phone home"constantly; but my firewall is blocking it.   Tired of INVASIVE JERKS
rate1 InstallShield Update Service Scheduler. Automatically searches for and performs any updates to software so you are always working with the most current version. omnipage among others installs it   chago
rate3 It appeared after installing Blackberry Desktop   airportbum
rate4 ISUSPM.exe is part of the FlexNet Connect product sold by FLEXERA Software (use to be Acresso Software). Flexera Software products offer solutions for software licensing, software entitlement, software installation, application packaging and software compliance ISUSPM.exe is a "Common Software Manager" used by many companies, Microsoft, IBM, AMD, … to manage installation, upgrades, and numerous other distribution related tasks On my system the process shows up with Dragon Naturally Speaking v 11 (C:\ProgramData\FLEXnet\Connect\11) It is reported to gather data such as OS, browser, time zone and language data from end user machines.  See also: Link   BigJohn
rate3 It appears that Adobe Connect web sharing service may use or may have installed this  See also: Link   Steve
rate4 Win 7 it installed in c:/programdata/flexnet/connect from dragoon naturally speaking which uses it to send advertising and updates to users. Did a regedit of run found it listed there. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run   azwildbill
rate5 Sucks up all computer memory at start-up on XP. I have let it run a few times and it ran for several days before I did and end process action.   KGJ
rate0 AVG detects ISUSPM.exe and considers it a threat. It doesn't seem to done my computer any harm,but,like many contributers here, I'd rather not have too many "nanny" programs running. Microsoft is bad enough.   Zed Too
rate5 Installed without Admin permission by Vodafone broadband lite shop Mar 2012. Activates across every software selection by operator on XP OS. Bad news if you are working against the clock. Should be classified as illegal Malware.   Roddy
rate5 Is installed by programs without permission, because it was used by the programmer as an installer. Then the program will interupt and ask for discs, etc, to force a user to correct or buy software. It can function as Adware if the programs it "updates" want.   bob johnson
rate3 It is very annoying, always showing up whne i turn on my computer   Sarah
rate4 Looks pretty bad. Have client's dell laptop. RKill stopped isuspm.exe. Found uninstall program on Flexera Software's web site (see link). Ran the uninstaller but it left the program files in place. Renamed the .exe to .ex1 in case it was "needed" later. System seems much faster now.  See also: Link   Pjbeee
rate4 You dont need it for any process as experienced I.T Tech Support You can just disable it   Tech Support
rate4 It installs without user's knowledge, has no working uninstaller and can only be removed with in-depth IT-knowledge. Fortunately, it does no harm. TO UNINSTALL, start looking for ISUSPM.exe and delete the whole directory (unlock files as necessary), remove the files from system start via msconfig and remove all registry entries (there are a lot!) related to these files and the directory.   Ralf
rate5 I downloaded a roxio 30 day trial and I`ve had the trial for much longer than that I suspect if I use the ISUSPM.exe update the will void the roxio trial or worse my rule of thumb any update or popup like java update or such I ignore them if something becomes so outdated it ceases to work simply go to said site and retrieve the update safely. don`t fix what aint broke. like grandpaw said. I say dangerous because I`ve been stupid and its just not worth the risk   native applaichain american
rate5 runs at startup, then makes itself invisible. No respectable software should do that.   Joaren
rate5 It doesn't seem to anything good and is suspect for error creation.   A J Risser
rate3 It occurred in my running programs after I installed and used Driver Genius Professional Edition. So I think DG activated it to automatically update the drivers.   Jos G
rate4 as others have said, it is used to monitor for updates after installs of certain programs "so companies can keep in touch with their customers" per their site. lol. just click on this link and they provide link to remove it from the registry to prevent automatic operation but leave the file in case you try to update from within the offending programs that installed it. takes 30 seconds max!  See also: Link   William
