Is there a 32 bit version of CUDA 7 for Windows 7? I’m trying to install the download version, but it requires 64 bit.

There is no version of CUDA 7 that is intended to be installed in a 32-bit windows OS. This is referred to as “Native” development, and it is unsupported on 32-bit.

"Native development using the CUDA Toolkit on x86_32 is unsupported. "

You can still create applications that can run in a 32-bit windows OS, but it must be done (with CUDA 7) on a 64-bit OS. This is referred to as “Cross” development (x86_32 on x86_64)

There are various previous CUDA toolkits (e.g. CUDA 6.5) that are installable and usable on a 32-bit Windows OS.

Will CUDA 6.5 work in VS 2013?

The getting started guide for windows that shipped with CUDA 6.5 will indicate which versions of VS are supported in CUDA 6.5
