I had this problem also, do you have an existing GAE installed? or GAT?

you can run the installer with msiexec -i /vi*x packageinstall.log to get a lot more information. I did all kinds of crazy registry edits and and other articles found on the web.

My question to MS is here

Finally after running the force uninstaller (as mine said it was installed but not functional) I finally got it going.

Guidance Automation without proper guidance, that is. I just uninstalled it. This is clearly a buggy software from Microsoft.
