You landed in the wrong forum for that question, but I really need to ask why you would need to install a 1996 program in 2023.

Did that come on a floppy disk?  

It's on CD

I need to open files from 1996 

If you cant get it to run from the autorun.exe file on the CD and dont know an IT person with some tricks up their sleeve, youre probably out of luck.

But 1996 is too old for Intuit to support.  So even if you could get the CD to install, there wouldnt be any updates available so the chance of it being fully functioning would be slim.

Doubtful. This is why I used to keep older PCs, like Win7.

Not any more. 1996 is too old to care about.

You seem to be lost on the internet.
