If already covered, please refer to or combine with thread. Will 3.2 retain 3.15 database or will the entire learning process need to be done again, all settings need to be made again?
In safe mode, I copied pghash.dat and pguard.dat from the system32 folder into my documents and uninstalled version 3.15. Rebooted normally and installed version 3.2. When version 3.2 was up and running, I rebooted in safe mode and copied pghash.dat and pguard.dat back into the system 32 folder. HTH
I used the uninstall from PG's start menu and on installing 3.2 everything was intact. license and data. I had a backup ready but it was not needed.
