If you get this message when you run ScreenCamera then read the instructions bellow.

ScreenCamera installer tries to install ScreenCamera IM Device driver, and if you have explicitly enabled the option Windows has of only installing signed drivers then ScreenCamera installer was not able to install ScreenCamera IM driver. Without ScreenCamera IM Device driver ScreenCamera can not work.

To solve the problem, go to:

Start > Control Panel > System > Open the Hardware Tab > Click the 'Driver Signing' button > Select the 'Warn - Prompt me each time to choose an action' > Click OK > Re-install ScreenCamera and when asked by Windows whether or not to install the driver click on the 'Continue Anyway' button.
