To upgrade the program you just have to install new version to the same folder as before over the old one, so:
- Download new program installation archive PGPRO.EXE
(for 64-bit version download PGPRO64.EXE instead)
- Save all unsaved work and close down all other programs before starting the installation process.
- Double click on pgpro.exe, follow instructions on the screen and install the program to the same folder as before over the old version.
- If prompted to restart the computer do so.
