What can I do when the NVIDIA software installation fails?
The installer package of the NVIDIA GeForce Experience application or the NVIDIA Graphics Driver can sometimes hit generic failures which do not pinpoint an exact error condition. These errors can be caused by an incorrect system state.
If the software installation fails, the best first step is to reboot and try the installation again.
If that doesn't help, try explicitly uninstalling the previous version (if any), rebooting, and then reinstalling.
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.
After all services are stopped, make sure 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.
Make sure to remove the following registry keys if they exist.
Run Regedit and search for each key, then delete if found.
Now try to install again.
If the above steps do not resolve the issue, uninstall all NVIDIA programs using the Windows Control Panel, reboot, and then try steps 1 to 4 again.
