Can 64-Bit Software Run on 32-Bit OS?

32-bit64-bitcpuUbuntuwindows 7

I have a 64-bit machine that has Windows 7 32-bit and Ubuntu 32-bit installed as a dual boot setup. Can I run 64-bit software on top of these 32-bit OSes, or are they a "bottleneck" limiting the true capability of the underlying hardware?

Best Answer

In theory I think no.

But one work around is to run the software in a 64-bit VM hosted on your 32-bit OS since you mentioned that your machine itself is 64-bit.
