I tried to use the safe exam browser today, but i only get a black screen.
Now I have this problem:
I can't even shut down my computer.
I can't LOCK my PC.
The task manager is also blocked.
I tried to uninstall the program to fix the problem. but it doesn't work.
Found a solution in the documentation:
There is also a command line tool which can be used to reset those values for the unlikely case that the SEB Windows Service didn't work properly or was damaged and can't be run anymore. This tool can be found at the following directory path in your Program Files directory:
SafeExamBrowser\SebWindowsServiceWCF\SebRegistryResetter.exe
But Thx!
