I've tried installing AVG Internet Security 2016 (USB Stick) for hours now, and it keeps saying - 0xC0070643 Event exec_finished

I have tried using:
AVG BFE Fix tool
AVG Remover
Downloading it from the webiste and installing that

And nothing helps, I still run into the same problem.

I am running Win 10. And there are no other anti virus programs on my PC, and Win Defender is turned off.
