No, a 64bit executable is a 64bit executable is a 64bit executable. The two separate directories exist to make it easier to maintain a 32 bit and 64 bit copy of an application, as far as I can tell.

You will need to recompile your things for 64bit, as the location of an executable makes no difference to how it is executed.

As you need to recompile a 32 to 64 windows driver you will need to do the same for a application, all variables from your code will need to readapt to the new 64 reality.
