Being a technet member, I gained access to Windows 7 RTM on August 6th. Naturally I tried to break it as soon as I could. It runs great on my Acer Aspire One Netbook, and an older Toshiba laptop. Over the last weekend I tried it on my main desktop. This is an AMD Phenom II X4 810, on a Gigabyte GA-MA790FXT-UD5P socket AM3 motherboard. Everything has been great except Virtual XP mode.
When testing one of the RC versions on the same system, it had no problem running at all. It was a little slow, but is was an RC version so I didn't think about it much.
I went to load up XP mode on the 64bit version of Windows 7 RTM and it comes up with an error:
Cannot start Windows Virtual PC while another virtualization software is running. Please close the other virtualization software and try again.
This is a clean install, with Office 2007, RealVNC, and Avast anti-virus only installed. I thought VNC had something to do with it, but it did not. I seached for the exact error message and came to the following Technet site:http://social.technet.microsoft.com/For ... 73d9a12030
It seems that everyone who has posted this error is running on Gigabyte motherboards. I have confirmed that running XP mode on an Asus board with the same CPU works very well.
Gigabyte has told me that since Windows 7 has not been released yet, there is nothing they can do about it, and has even asked me to check that maybe AMD has the problem. I informed Gigabyte again that I am a Technet member, and it is the official release. Since I have not seen this reported anywhere else, I figured I would start with TR forums
