InstallShield Update Manager – ISUSPM.EXE
Isuspm.exe is the InstallShield Update Manager. InstallShield is a very popular program installer. Chances are good that you have lots of programs on your system that used that as the program installer.
Isuspm.exe can be used to check for updates or additional product information. When an update is available it is listed in the Update Manager. This link, when clicked, will take you to the download and any release notes or other product information.
Another file called agent.exe is the Update Agent. This is needed to download the product updates. If you like this update capability, then leave both of these files in place. If you don't care for it, then we'd recommend removing both using WinPatrol.
You'll find additional information about these files at http://www.installshield.com/products/updateservice/. Installshield has been acquired by Macrovision.
