Go to Control Panel > Users > Change User Account Control Settings

Slide the setting down to "Never Notify"

Restart and try.

Because it runs "STOM^.exe" in the RB folder that is an exe file

that 7 will block, if that works set UAC to the first one up,

then it should bring up the dialog box "Do you want to allow STOM^.exe"

click yes.

I'm using it on 7 64bit
