The file s32cmpex.dll is part of a Sentinel System Driver from UCS. This file is used with USB dongles that act as security devices for certain programs. A USB dongle is a small USB device that plugs into your computer using the USB port.
When a program requires a dongle, it will not run if the dongle is not plugged into the port. This is a security method to ensure that software cannot be illegally copied, because the copies will not run without the dongle. This file is part of the driver that allows your computer to recognize the dongle.
If you get an error with this file, the software that needs the dongle may not be able to run. You may be able to fix this issue by cleaning your registry. The registry is a database on Windows that tracks all the files installed on your computer. If there is a mistake in the registry, Windows won’t be able to find or use the files needed to run programs.
