The old serial Hi-Pro cost less than the newer USB Hi-Pro. Though, I would stay away from the old serial Hi-Pro because you give yourself hardware compatibility issues. See this post. It’s difficult enough without adding hardware issues to the mix.
Also, this has nothing to do with 32-bit versus 64-bit. The only issue there is whether the fitting software is written to run on a 64-bit system. For example NSFit from LoveHearing/NewSound would not run on a 64-bit system.
Thanks for the info.
Another forum member I have talked to has a serial Hi Pro and runs it on a modern laptop using XP. The Hi Pro is operated using a USB adapter with no issues. That is why I made mention of the Vista issue. I feel like there is an issue with Vista and maybe Windows 7 with the older serial Hi Pro’s.
If I had it to do over I would have bought the newer USB Hi Pro. I do not make a living with this Hi Pro, so not a big problem. It is working great for my purposes.
