Usual issues are with anti virus applications who block the process of CGAC as it "enteres your PC". Try disabling any AV during the installation, there is also an issue with ASUS boards as far as I heard. You simply need to uninstall the ASUS "suite" or something, try uninstalling this if you have it.
I know that the AV could be a problem, this is not my first problem with CGAC. That's why i changed my AV previously to Kaspersky and after that all worked fine for me. And I had the AV and the windows firewall turned off like all the time when i run CGAC cause I know it could cause problems.
And i dont have an ASUS board.
