If you you are seeing the 0x0003 error when attempting to open your NVIDIA Control Panel, there is an easy fix. First, don't simply delete the app and reinstall as you are still leaving plenty behind in the registry et al.

Download the latest NVIDIA driver package for your card. You'll need to install both, the video driver and control panel package (not just the driver). When prompted for an "Express" or "Custom" install, click on the "Custom" option. Next, select "Clean" install from then dropdown.

Works for me.
