Intel GPA version 2012 R1 has not been validated with Microsoft Windows 8.
There are multiple pieces of software that Intel GPA needs in order to support Windows 8 (drivers, the OS, etc.). All of these are changing very rapidly, and all of these are "beta" quality. As you might expect, Intel GPA requires access to OS and driver features and functions that are not typically utilized by normal beta testers.
We understand the importance of supporting this platform, and we will let you know when we have a version that works with this OS.
ps-> By the way, what graphics chipset or discrete graphics card are you using?
The processor is Core i5 2405 w DH61AG motherboard. No discrete graphics card was used. GPA 2012 R1 worked on Window 7 64-bit no problem. Win 8 preview was upgraded from Win 7 64-bit. All drivers and apps were upgraded as well. However GPA simply can not launch anymore.
