Close the launcher.
Open task manager by pressing [Ctrl]+[Shift]+[Esc] together.
Go to Processes.
Right click on ZoCrashReport and end the process.
Restart the launcher.
The game should now update and patch.
If you are still having issues, you can also look for duplicates of any of the following files: eso.exe, awesomeium.exe, and bethesda_launcher.exe.
If that still doesn't help, try the steps here for Fatal Errors.
