Notes on Operating System Compatibility
Windows
Versions 7.2 and later of WinRATS run properly on all recent versions of Windows, including Windows 7, Vista, and XP, as well as Server 2003 and 2008. They should also run properly on older versions, 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 Vista subsequent versions of Windows. Two 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 Vista (or later), 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.
Macintosh
The current versions MacRATS are "Universal" OS X application, which means that they run natively on both Intel-based Macs and on older PowerPC-based Macs. However, they do require version 10.4 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.
