Thanks for the suggestions. I had a couple ideas to have 2 separate .psf files....one for 64 & 32bit. Then add a conditional statement in the bat file to determine the machines platform type and which .psf to use. This worked and I think that this is the route we'll take.
I do realize that software exists for Pro/E 64-bit, but our models are relatively small and the benefit would be minimal (plus we'd rather not maintain both). Our 2 64-bit workstations were just for evaluating this platform a few years back, but now need to run 32bit Pro/E.
Thanks again,
Mike Bills
