I was reminded again today about the reason we’ve been recommending that clients continue to ask for Windows 7 32 bit. We were helping a client install PFW for Windows 5.9 when we got a “Runtime error 449” (I think that was it). A Google of the error returned the information that 5.9 client was evidently not compatible with Win 7 x64.
Until all your software is up to date, and all your printers are new, we still recommend that you order 32 bit. Yep, it’ll be older, but it might just work with your software and printer drivers.
