Why can 64-bit Windows run 32-bit programs, but not 32-bit drivers?
A computer can run 64-bit programs and 32-bit programs at the same time, but a single program can't run both 64-bit and 32-bit code because the way they store information in memory isn't compatible. Different programs are allocated different blocks of memory to use, so it doesn't matter that they…
The Short Answer
A computer can run 64-bit programs and 32-bit programs at the same time, but a single program can't run both 64-bit and 32-bit code because the way they store information in memory isn't compatible. Different programs are allocated different blocks of memory to use, so it doesn't matter that they aren't compatible because a 64-bit program will never try to use the memory from the 32-bit program. Drivers run alongside the core Windows program (the "kernel") so they need to match Windows in order to work.
