new version unable to open files

SUGGESTED

We are updating from Sage 50 Premium Accounting 2013 Server Version  (company files on a mapped drive) to Sage 50 Premium Accounting 2022 Standalone.  I copied the files off of the server on to a network drive, maintaining the folder structure.  When the user goes to open the company file, the program shows: "Opening database. Please wait...."  and eventually comes to this error :

Since its a local copy of the file, I don't get this error.  Any ideas ?
