Checking Administrator privileges ERROR // How to fix it's
Checking Administrator privileges ERROR PB : how to fix it's program now!! and how to change line ETC. /
As I understand, you are trying to install PunkBuster. Can you try to run PBSETUP installer as Administrator? If that doesn't help, try to start your PC in safe mode with networking using this manual: https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode and install PB.
I hope this helps.
