The supported hardware and software platforms for Sage MAS 90 have been updated as of 12/31/09. The list below shows exactly what configurations Sage support.
Note that Windows 7 is stated as not supported with versions prior to 4.3.
Tip: While we do not recommend running MAS 90 on un-supported platforms we’ve found that you may be able to run it on Windows 7 32-bit (avoid 64-bit) by using the MAS 90 CD to run workstation setup on each of your stations. If you don’t use the CD you’ll likely receive some type of error (under Windows 7) about the workstation not being able to map to the server.
