It comes packaged with many products. It isn't necessary to the application only an updater for Nuance software. I wouldn't leave it because it is just another program taking up resources.
Totally intrusive scanning of all my running software and annoyingly pops up with messages on what supposedly needs updating. Is this a way of Flexera trying to penetrate the Software Asset Management market in a sneaky way perhaps?
windows installer keeps launching it over and over. We end task it and it comes right back. We had WinDVD and it did not uninstall clean! ARRRGGHHhhhhhhhh
This is a memory hog. It is resource intensive. It is spyware. Nuance bundles it with Paperport and other products. If you are a registered owner of Nuance Products complain to them. I believe it is spyware looking for hot software. There are better ways of forcing purchase than this BS

i am summarizing all the comments into this one. "it runs at startup, then makes itself invisible. No respectable software should do that." "cannot easily uninstall, ... does not ask permission before installing thus fills every definition of malware." the fix: (i am running xp) run regedit, navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run and deleted the key ISUSPM in C:\Documents and Settings\All Users\Application Data\FLEXnet\Connect\11 make each of agent, dwusplay, isdm, issch, and isuspm a null file, then hid and write protected them. i used notepad's 'save as' option with save as type 'all files' to overwrite them. open a command window: C:\Documents and Settings\All Users\Application Data\FLEXnet\Connect\11 attrib +h +r +s isuspm.exe for each of the offending applications. delete the contents of windows/prefetch, where you'll find the only copy of isuspm.exe note: you may have to do this under safe mode if you get an 'access denied' error message note: i used this same process to get rid of the annoying java update popups. the only way to get rid of jusched and jucheck, as unchecking the update checkbox is futile. hope that helped.
I have a rootkit killer application and it took out things from the registry I didn't even know where there. It was even looking for the ISUSPM.exe (which I had previously renamed .ex1 as suggested before). Whether used by many S/W packages doesn't count if it gives you grief. It was put by Dragon (11).

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!

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.

Best practices for resolving ISUSPM issues

A clean and tidy computer is the key requirement for avoiding problems with ISUSPM. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the ISUSPM.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
