Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Forum Index : Microcontroller and PC projects : Windows 10 compatibility with old(er) software.

Hi,
I have recently updated my PC to a Win 10 64-bit machine, but would like to work on some old assembly code projects originally made on my old XP 32-bit wonder, which ran Microchip's old MPLAB v8.91 software.

I would very much like to use the old MPLAB software, rather than convert the projects to new new ones using the current MPLAB X v6.00 software.

Before seeking out the old MPLAB version for download, please can you advise me if this will be practical on my new machine. I gather there is a "compatibility mode" requirement here, but know nothing of its capabilities !

With regards, Paul.

If you assemble 32-bit code, it should work. Win 10 64-bit and Win 11 (there is no 32-bit Win 11) won't run 16-bit software.

Haven't tried using it in anger recently but MPLAB 8.92 opens fine on W11. No special mode needed.

Hi toml and Peter,
Thanks for your replies. Encouraged by your posts I have downloaded and successfully installed MPLAB v8.91, and loaded and assembled one of my simple old projects with almost no pain at all! That's amazing and not really what I was expecting!

The application went into the "(X86)" program files folder as expected - presumably for 32-bit programs. I have 2 drives on this machine, a C: - SSD, and a conventional D: - HDD. I got a moan from MPLAB because it couldn't find the old C: files to delete before assembly - I can live with that!

Now to try a more complex project - which draws code from my library.

With thanks, Paul.
