After further investigation it appears the error is caused by security not allowing a file to be created... starting the Demos with "Run as Administrator" option allows the app to run.

This is the full exception from the event log:

I can confirm this error on both: Windows 7 32bit, Windows 7 64bit and Windows 8 Release Preview 64bit. The "Run as Administrator" does help this issue, but the crash should be fixed none-the-less.

Best regards,
