Is it possible to install only cuda toolkit 32 bits on a 64 bits computer ? and work only on 32 bits ?

Because i’ve got too many incompatibilities …

Yes it is.

64-bit drivers (if you are running 64-bit OS)

32-bit cuda toolkit

32-bit SDK

When you compile, you must compile as 32-bit application.
