You need to disable the UAC of Vista, in order to use the Weavefuture Internet Cafe PC Game Kiosk Timer.
1. Launch MSCONFIG by from the Run menu.
2. Click on the Tools tab. Scroll down till you find "Disable UAP" (this should probably change to UAC in next Vista beta builds and in the RTM version). Click on that line.
