Update :- After thinking about this and some trial and error, I have managed to half solve this issue. I now have it working provided you install it via the MSI option. I haven't yet managed to solve Streaming it from an EXE file yet, this still fails to quit
So in case anyone else needs to do this here's the way I did it on my Base Win7 64 Bit capture machine:-
Once this is done I can install the Thinapp MSI package on my W7 64 bit linked clones and everything works as expected, but interestingly when you right click the Skype on the Taskbar and select Quit Skype you see the Thinapp popup message in the bottom right hand corner of the screen appear again. If anyone gets the Streaming version to work I'd be interested to know how.
