If you downloaded "PRA*.7z" file, uncompress it and copy suitable 32bit or 64bit PRA.exe and PRA.pdf files to any folder. This program is portable and all settings are saved in the "PRA.ini" file located in the application's directory. For help see "PRA.pdf" included in the package.

If you downloaded one of the installers (thanks goes to Inno Setup), just run the "PRA*Setup*.exe" program and follow instructions. Installer will make links to the PRA application in menu and associate PRA with ".pls" files. It also produces an uninstaller program.

For additional information or if you may have any comments and suggestions E-mail Marek Dolleiser.

Documents (.pls and .ini files) created by the different main versions of PRA are not compatible. If you have files created by PRA version above 10 you can still open them in PRA version 19. However, most of the settings which have been saved with the data will be ignored. PRA version 9 is not compatible with any newer version.

 Download older version of PRA if you need it for any reason.
