Windows XP forum: Converting 32 bit to 64 bit

Great long-term support... At least I finally have a DX10 excuse

because of a lack of support.

Greetings, I have a question along the same lines, thus I thought I'd post here.

I have a couple old c++ programs I made back in the day that I'd like to be able to run. I have a 64bit windows 7 machine specifically home premium. The programs are made 32bit and throw an error when I try to run them. They're small, kind of pointless, and almost purely for nastalgia. Hence it's not worth it to me at the moment to set up xp mode, or a virtual machine. At least not just for them. I tried to run the in "compatibility mode" which was ineffective.

So,
A. Is there a way to convert a simple exe to be compatible with a 64bit machine? Even though it stays a 32bit program?

B. I don't think it exists, but is there a way to compile a c++ program online? And if so, compile it in a 64bit format?

C. Do I just need to own up to reality, and get a virtual machine in 32bit?

Thanks for the help! Google, the all knowing oracle, didn't show any results for my several searches, hence why I'm finally posting here.

Cheers!
