Joseph, Further to Blue's message, you can do a copy of the whole Roots 4 directory (program, databases, everything) to your new machine, install a fresh copy of UFT, and then use UFT to access your data in the Roots 4 directory. If you set up the appropriate .bat file, you can start up Roots 4 in a DOS window, or you can set up an icon on your desktop to launch a DOS window running Roots 4 pointing to your project. You can use UFT to update your data and then see the results in Roots 4. (Just don't try to run both at the same time.)
While running Roots 4 in your new Windows machine may not be particularly useful, it's nice to have a second method of checking your data, as a backup.
