No choice but to use PBP on 64 bit versions of Windows

My 32 bit machine died so I was forced to buy a new 64 bit Windows 7 machine, now I'm frustrated to find after reloading everything that PBP no longer works. I get an error that PM.exe cannot run due to an incompatability with Windows 64.

I found something that stated I must use MPASM rather than the PM. So I set that option in MicroCode Studio. That helped, but I now get 456 assembly errors. MCS does not copy so I cant paste them, but they start with "Cannot open include file P16F876A.INC" and most of the rest are symbol not previously defined.

I've searched the computer and there is no P16F876A.INC, not even in Microchip folders. Please advise!

Thanks in advance for your help.
