Notes on Operating System Compatibility
Current versions of WinRATS (and all versions from 7.2 on) run properly on all recent versions of Windows, including Windows 8, 7, Vista, and XP,
as well as Server 2003 and 2008. They should also run properly on older versions of Windows, including Windows 98 and NT, but we have not done any
formal testing on those platforms.
Versions 7.1 and older
In general, Versions 7.1 and older of RATS should run well on 8, 7 or Vista. Three known issues:
- The Help system in Versions 7.1 and older of RATS used the WinHelp (.hlp) format. Microsoft did not include support for WinHelp files in Vista
(or Windows 7) by default. If you have Version 7.1 or older and want to view Help files under Vista or Windows 7, you will need to download the
WinHelp viewer from Microsoft. See Microsoft WinHelp. Beginning with Version 7.2, RATS help was provided using HTML-based .CHM files, which Vista and Windows 7 support by default.
- In Versions 6.3 and older, the "Printer" button did appear in the Print Setup dialog box when running under 8, 7 or Vista, so you could not change
the destination printer from within RATS. This issue was resolved in Version 6.35 through the use of a new File-Print... dialog.
- In Versions 5.1 and older, the installer won't run on Windows 8, 7 or Vista. The software itself will run if it's copied over from a computer on which
it's already been installed, but the old installer doesn't comply with the requirements for software installation on releases of Windows which came many years
The current versions of MacRATS are "Universal" OS X applications. The Pro level of RATS includes both native 64-bit and 32-bit executables (and will
run the 64-bit automatically if you have the hardware), while the Standard includes just the 32-bit executable. The current releases require version
10.5 or later of OS X.
Version 6.3 of RATS was the first OS X-compatible release. Previous versions required OS 9 or older running on PowerPC systems.
