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?
Solution:
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.
