Yes, I have a valid license windows 7.
The reason I changed back to my XP, simple this, I'm not to conversant with Win 7, my modem and bookmarks are on there, I have internet security, don't like browsing without AV ect, I use IDM when I down load ect ect. any file I down load I can scan, I wasn't installing my AV on this machine until it all worked. I live in Africa we have many problems with power and ISP connections.
I will reinstall it again, I did install the first time as 32 bit, then i reformatted and install 64 bit still the same.
