    You might want to make sure that you got the drivers for the mobility graphics card (new catalyst drivers can be found here (64-bit) and here (32-bit)). Also, please run the program as administrator because it might be that you don't have sufficient privileges to install the drivers.

    It says your drivers are not signed? Where did you download them from? Have you tried a different download?
