I hae a software that is 64-bit but my computer is running widows vista 32-bit. I have windows xp professional that I can install but I want to find out before if it is 64-bit. It is on a dvd, how do I check it?
Windows X64 has a "Readme.htm" file in the root directory of the disc. In part, it will read:
"Readme for Microsoft Windows XP Professional x64 Edition
For important information that you should know before you install this product, see Pre-installation Notes for the x64-based Versions of the Microsoft Windows Server 2003 and Microsoft Windows XP Professional x64 Edition Operating Systems." (and it goes on from there).
