Problem

I see a "low disk space" notification everytime I insert my license dongle.

Solution

The "low disk space" notification is being thrown by the Windows operating system, and can be safely ignored, when it is referencing a license dongle.

If you would like to attempt to suppress the warning, then please see optional steps in this help link from "WIBU".
