Peachtree 2009 Install error

SUGGESTED

After installing a new computer for a client, I was unable to transfer Peachtree 2009 over to it using Laplink PCMover, which is what I normally use for applications. Unfortunately, I was receiving an error about too many users. After finding another post here about that same issue, I tried uninstalling completely and reinstalling. I used Revo uninstaller to remove all remnants of the software, minus the company files, and then reinstalled Peachtree 2009. The installer gets most of the way through now and throws an Error 1639. 

My client is willing to upgrade to a new version of Sage if need be, however, I would like to fix this issue if possible. Any Suggestions?
