Yes, it's possible to have both version on the same hard drive, just not in the same folder tho. I have 5.5 and 6.1 on my hard drive. I installed 5.5, well, that was the first one. Then I upgraded to 6.1 but the upgrade is to another folder. They play together nicely. Maybe you could install 5.5 , wait a day or so, then try installing 6.1 afterward??? :tongue1: Just kidding . Make sure you didn't install to the same directory/folder.
