Is GRTF Friendly to 64-bit Win7?

Hi,
It's a wonderful toolkit. I tried running the studio but it keeps crashing when it has something to do with XNA. I installed both XNA framework 3.x and 4 redistr but the app still crashes. I did a dependency walk and it complains that this app is unfriendly to x64 platform.
Can anyone help?
Thanks in advance.
