Hardware and software requirements:

A PC with a sound adapter running WindowsXP or higher operating system including 32bit and 64bit versions. It also works on Linux boxes with Wine. PRA version 17 requires 1.9 GB of free RAM, versions 9 to 16 are happy with 0.9 GB.

Download PRA:

Documents (.pls and .ini files) created by the different main versions of PRA are not compatible. Please delete "PRA.ini" file from the program directory if you are upgrading PRA main version. Version 17 is the latest one which includes most features. If you have files created by PRA version 10, 11, 12, 14, 15 and 16 you can still open them in PRA version 17. However, all the settings which are saved with the data will be ignored. Version 9 (requires 50% less resources and produces smaller document files) is still maintained (bugs fixing only).

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.
