The accounting program (ACCPAC) will run on a 32 bit machine but generates op code errors on a 64 bit machine. I have had to resort to running it on the one 32 bit machine remotely via ssh. It is likely a memory management issue that has never been fixed. Yes, some programs will run on a 32 bit machine but not ones that require larger memory. I have tried all different configuration combinations, but after wasting a lot of time, I just bit the bullet and ran the accounting program on a 32 bit machine.
