That’s good. I was thinking perhaps it was downloading the incorrect version.
If you install an older driver does the latest one then install?
You might have to reinstall an older driver via the device’s entry within device manager.
Right click device.
Choose update driver.
Choose ‘browse my computer for drivers’.
Choose ‘let me pick from a list of available drivers on my computer’.
Choose the compatible hardware from the list, then choose next.
Choose one of the older drivers from the list shown, then click next.
This will then reinstall the driver.
Are you using any third party antivirus software? If yes then perhaps this is blocking the install.
There may also be a problem with that particular driver. Have you checked the nVidia forum?
