Windows 8 64bit + Quadro K5000 touch wont start

Trying to install touch .77 on windows 8 machine. Have the latest drivers from nvidia for the quadro k5000. Install goes smooth, but when I try and launch the program touchkey.exe freezes instantly and I’m not able to input any data into any fields. I’ve tried installing different builds and the same issue happens. Was really excited to test out the k5000! Anyone else have this issue ?

The K5000 required a drastic change to the way we do something in TouchDesigner, so that work only went into 088.

works fine on my 077 system, could be a driver thing?
