Ver 1.5 won't run on Win 7 and Gerber won't even talk to you.
Does your edge use a parallel port ? I'd be willing to bet the new
computer doesn't have one
I think there's going to be a bit of a learning curve to use flexi.
I think you would be better off finding a used
computer with XP or something lower from Ebay
and continue to use the Gerber software.
