How do I run Traktor Pro 2 as 64bit?

I am running Traktor 2 Pro on Win 7 64-Bit without any problems. Not a single crash nor any issues.
The main advantage to use a 64-Bit Windows is: you can use more than 4GB of Ram.
If you want to switch from a 32-Bit to a 64-Bit Window, you have to reinstall your Operating System and all your other Software. Quite a bit of work.
If you run currently Traktor on a 32-Bit-Windows without problems, there is also no need to change.
