Solved Error Code: 0301 CDEF0008 (Windows Test-Signing Mode)

Hello,
since Today after I installed GamezBD, I get this shit Error Code.
My Windows Build is Windows 10 20h2.
I tried the Solutions from this Thread: https://forum.gameznetwork.com/threads/error-message.237282/
but nothing helped.
I hope someone can Help me so i can Play GamezBD again.

 

Problem still not solved

 

You have to turn Test-Signing Mode off, because GameZBD does not support test-signing drivers.
Press Windows + S, type “command prompt” in the dialogue box, right-click on the application and select Run as administrator.
Once in elevated command prompt, execute the following command:

Code:

bcdedit /set testsigning off

If this command doesn’t work, go ahead execute the following command instead:

Code:

bcdedit.exe /set nointegritychecks off

Restart your computer after executing the commands and try to run GameZBD. Check if the issue is resolved.

 

Tried it but still the same Problem. I tried your Method with Windows Update 20h2 and now with Windows Update 21h1 and still the same shit Error
