The folks who say Peachtree is NOT compatible with Windows Vista - ARE 100% CORRECT. My company does software, networking, servers, etc. and Peachtree is by far the worst we've seen. You can get it to run but it will be far from stable (read as: work one day and not the next). But by far the worst problem is Sage software (Peachtree's parent company). In addition to Peachtree they own a number of larger accounting software titles and they, not Peachtree, will get priority in all new development. So all the owners and purchasers of Peachtree will just have to wait in line. If you buy this package and try to run on Windows Vista, don't say you were not warned. To those who say it will run on Vista, I say don't give folks false hope, there is a big difference in being able to run and being able to run correctly. Now if I can just get down off this soapbox without falling....
