I had a problem with Peachtree today and after some head scratching I managed to come up with the solution so I thought I’d make a post about it. The error occurs when you try to open up one of your existing companies. A dialog box appears that says “This is not a valid Peachtree company.”

Nearly everything I read said it was a problem with the attributes on the folder containing the company files. I spent too much time following that advice and it ended up being a deadend. The real solution was a corrupt (or in my case, missing) file called VERSION.TXT in the company directory. I simply took the VERSION.TXT file found in the directory for the sample company that comes pre-installed with Peachtree, copied it into the directory for the company that wouldn’t open and everything was good to go.

This problem happened on a copy of Peachtree Complete Accounting 2007 but I’d bet it will solve the same problem on any version of the software.
