Thanks for the help! There was no other partition on the list and at least for now 32 bits is all I need so I ignored the odd looking (WIN7) that came after the "C:\" prompt, then it installed with no errors!!
MASM was one of the first languages I ever learned. But that was back in the days of the first IBM-XT clones. I then migrated to Turbo Basic then Power Basic that allowed using Assembly code to be used. Later I had to become proficient in Visual Basic 6 and used that exclusively, so as you might expect I'm a little rusty in Assembly coding. Now that Microsoft killed off Visual Basic 6, which does not even work properly anymore in Windows 10 it is vital that I become proficient in another language or go back to using MASM. In my case the
software I program is not overly complex but requires a large amount of bit manipulation, which is usually slow or cumbersome using high level languages. I miss the fast and simple bit rotations & left/right shift of Assembly.
After trying out a "hello world" for a number of alternatives including Java, Python, CUDA (I have a GPU installed) it seemed best that I also give MASM32 a try. It's not a cross platform language, but with the way higher level languages come and go I at least know that Assembly will be around for awhile. It was also relatively easy for me to recode for a new platform, although it's hard for me to know whether that is still true. In either case I'm thrilled to have the nice looking MASM32 editor on my screen and now I can't wait to try out a few of the sample programs.
