Officially:
5.5 runs under Windows 2000/NT SP3/98/95
6.0 runs under Windows 2000/NT SP6/XP/Me/98
7.1 runs under Windows 2000/NT SP6/XP
So 6.0 and 7.1 should not be an issue and is officially supported. 5.5 might work because XP is based off of 98 technology but its since its not officially supported you wont be able to get technical support for issues that arise...
