Not really able to acredit this application as I have only tried getting Sage Instant Accounts v11 and v12. The ability of this application to work under Crossover Office and indeed WINE is mirrored by Sage Line 50, in that I can get Sage Instant Accounts v11(not the plus version) to install and run (bronze/silver ish), whereas the v12 of the software doesn't want to play:(
If you are trying to get this application to run, then check notes under the equivalent version of Sage Line 50.
