I guess you know that there are two versions of the downloadable 3.1 patch. When you run the update it will search your hard drive(s) for the current version of UFT. If you select and try the wrong one it will do no harm - it simply will not work. The puft3ua.exe file is to upgrade version 3.0 which was distributed on CD (which I think is the one you want). The puft3ra.exe file upgrades version 3.0 which was distributed via internet. I'm guessing, though, that if the one for a CD didn't work for you, you can try the other and see how that goes.
