Hi You can download version 14.01.0289.007 Ru3-V3 and test it. http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=165 Do you see any other error from event viewer? Event 4999 just shows RpcClientAccess.Service error. Do you turn off any AV software and edge and try it again ?

I have installed this ru3-v3 but the version still shows as 14.01.0289.001?

Hi It is odd. Is there any antivirus software or scan software in your local network?
