Im Offiziellen NVidia-Forum steht folgendes:

"Scotty99 said:Just did this step by step and now my geforce experience says "Geforce experience encountered and error and must close". Do i need to reinstall it now?

im having the same issue, i uninstall and re-install but still not fixed. i havent had this issue until I tried to update to drivers version 347.52 any other advice?

I just talked to one of their online support people, and they said that the GeForce Experience server is down, and their engineers are working on it. That is why your app is crashing. No ETA yet.
