Cannot Launch Origin after installing BF1! .NET Errors and WerFault.exe errors

Hey, WerFault.exe is related to Windows Error Reporting, so potential fix is to try to turn it off and check if that helps. 

To disable WER pres Win+R, than type services.msc, than on long list you will find Windows Error Reporting, right click on it -> Properties ->  "Startup type" and select "Disabled" -> OK. 

Reboot you PC and check if error appears. 

I would not recommend keep it disabled at all times, as this is part of OS.

You can also check if same issue appears on new admin account on your PC.

Fingers crossed 🙂
