What is ISUSPM.exe and How to Remove It?

After installing some applications from Nuance like Dragon Naturally Speaking and Omnipage, you will notice an application called “Flexnet Software Update” or “FlexNET Connect Software Manager” has also been installed. This application is associated with the process name ISUSPM.exe and pops up during startup or normal use. Flexnet doesn’t have an uninstaller nor a start menu entry.

ISUSPM.exe is the InstallShield Update Service Scheduler. It automatically searches for and performs any updates to some of the software installed on your PC so you’re always working with the most current version. It may come preinstalled on your computer and also runs as a startup process. Even though users are not offered with a way to uninstall this, it’s not a various as thought by many.
