I dug out UFT 2.0 and installed it in a separate directory. (All on C: Drive). I then installed Retail UFT 3.0 as an upgrade to UFT 2.0. I then installed the Retail UFT 3.10 patch over everything else. The patch installed automatically.
But...Once the 3.10 patch is installed, the error message shows up if you try to reinstall the patch a second time.
Perhaps a few people have successfully and seamlessly installed the patch and aren't even aware of it yet.?? -john
