 Do note that on 64-bit systems, you need to go into the "Wow6432Node" under "Software". it's a specific sub-folder for the registry keys of 32-bit programs.

I explained the full procedure in this thread, and in the thread I linked to from there:

If (after correctly going into that "Wow6432Node"  folder) the required registry keys don't exist, simply create them.
