Peachtree 2004 "This is not a valid company" error

How are you getting the company onto the bad computer? Try making a PT backup file on another computer and then do a restore into a NEW company on the bad one. Your error message implies that you are missing a file on that machine which is causing PT to not recognize the company.

What I did was Copy all the data from the existing server and paste it all onto the new server. I have checked and I don't see any missing files but i will try the backup.

Is this PT complete accounting or PT accounting? If it is complete if you want, I could try opening the company file if you e-mail it to me at soundbookkeeping at gmail dot com. Just zip all of the files in the company folder if you don't have a working backup file (ptb).

It is PT complete.

Thanks for the tip. I actually found this one on a web site somewhere and I already checked. The version.txt file was copied over and it does have the same numbers as the old data files. I want to try creating a peach tree backup like Lara said and then restore the backup to the new server and see if that makes any difference. The problem is I need to get everyone out of the files in order to do the backup so I may do that this weekend.

Ruling out any network issues you might try that on a local computer first. Then take that new backup file and restore it on the server.

I'm not sure what it could be.
