I thought i was going to have lots of problems when I got my new computer. After reading all the "help" questions about XP, etc. I first installed my version of 3.0. Immediately went to download the 3.1 update. Everything worked and I didn't have to worry about any of the XP problems that others have mentioned. Hooray! So ... go to http://www.uftree.com/UFT/UFTProductInfo/TechSupport/uft310.htmlhttp://www.uftree.com/UFT/UFTProductInfo/TechSupport/uft310.html and update your 3.0 version to 3.1 and everything SHOULD be okay.
