Re: Running multiple versions of Quickbooks
hi @KristyG ,
As explained by LilyC , you are not allow to open the same file with different version (year). You may only open (not working concurrently) the same file on Pro/Premier with the same year.
Another thing, if you are still running QuickBooks on Win 7, you have to upgrade your OS or purchase a new machine prior to January 2020.
