No, if they go in you should be able to use add/remove as normal.
I got a reply from an nVidia bug report I submitted today (encouraging, I didn't think I'd hear back from them).
The suggested in addition to creating the -loglevel:6 log, to try the following (which seems to involve installing while in safe mode?)??
1.First download and install the Revo Uninstaller from here: http://www.revouninstaller.com/
. There is a 30 days trial period.
2. Restart windows in Safe mode with networking. You can do this by hitting the F8 key before Windows starts which will give you some boot options. Select to start in Safe mode with networking from the list.
3. Once in Windows launch the Revo Uninstaller tool.
4. Uninstall all NVIDIA entries. There should be a few and they all should start with "NVIDIA....".
5. After each one you uninstall, Revo will give you option to scan for additional registry entry. Do the scan for each component and then select all the additional left-over registry entries and delete them all. This way all traces of all NVIDIA components will be removed.
6. Navigate to "C:\Program Files" and delete the "NVIDIA Corporation" folder if it exists.
7. Navigate to "C:\Program Files (x86)" and delete the "NVIDIA Corporation" folder if it exists
8. Restart windows in Safe mode with networking again. If windows detect new hardware and prompt to install driver then cancel if you can but if not then allow it to proceed and complete first. Restart Windows in Safe mode with networking again if prompted, otherwise proceed to next step.
9. Re-install the 301.42 driver. When installing the driver, select the "Custom (Advanced)" install option and then put a checkmark in the "Perform clean install" checkbox.
--- my questions ------
1. I thought your guide stated that the new drivers would no longer install in safe mode? Did I mis-read something?
2. The RevoUninstaller tool is unknown to me? Is this their idea of a replacement for DriverSweeper? Are you familiar with this?
