Either:

 - Copy the files to the second workstation,

or

If the workstations are networked, set up a shared from the first computer (the 'server')

Set up the forms on the second computer and pick the forms from the first (server) shared volume.

If you will be logging into Sage from either workstation using the same company file, set up the shared form file in Sage 50 so that it is the same from each workstation using a 'UNC' file path.   i.e. \\firstcomputer\Sage50DataShare\Forms\MyInvoice.frm

Or, you can 'map' the same drive letter on each computer, so that F:  is the shared folder on the first computer, on either computer. 

we are not on a network so I copied the files.  Thanks!!
