WindowBlinds is installed correctly on this PC.

WindowBlinds has not been activated correctly on this PC.  Please activate it from SDC.

Your machine does not support per pixel borders on WindowBlinds skins.

This is because :

Your computer graphics hardware does not support acceleration of per pixel alpha.  WindowBlinds requires this for per pixel alphablended borders as without it performance would be poor.  Please see if you can obtain new drivers for your graphics hardware.  Recent ATI & NVIDIA boards should support this feature.  Onboard graphics tend not to.

You have one monitor in total.
