Error Message

Invalid License File <path of license file>\sc_xxx_yyyyy.scl

Cause

The license file might be corrupt and cannot correctly be read.

There could also be a missmatch between the number of the license file (xxx_yyyyy) and the recognized dongle number. Maybe, the dongle is not fully recognized.

Solution

Make sure only the correct dongle is connected to the PC. Check if it is recognized in sc_setup - Diagnostics - Dongle.

Restart the application. Occasionally, rebooting the PC could also help.
