The installer of the NVIDIA Graphics Driver may fail without pointing to an exact error condition. This may be caused by an incorrect system state.
If the driver installation fails, please reboot and then try the installation again.
If that doesn't help, try uninstalling the NVIDIA graphics driver and software, rebooting, and then reinstalling.
If it continues to fail, try performing the following steps to reset the system state:
1. Make sure that NVIDIA Windows services are not running.
To stop the NVIDIA Windows services, run "services.msc" from the Run window, then find and stop all services where the service name starts with NVIDIA.
2. After all services have been stopped, verify that no instance of any NVIDIA application is running.
To look for instances of NVIDIA applications, open the Task Manager and look for processes starting with nv or NVIDIA. Kill those processes, if any.
3. Remove the following registry keys if they exist.
Run Regedit and search for each key, then delete if found.
4. Try to install the driver again.
If the above steps do not resolve the issue, use the Windows Control Panel to uninstall all NVIDIA programs, reboot, and then try steps 1 through 4 again.
