Troubleshoot: WCF HTTP Error 404–Not Found

Copying from MPPVE (formerly RCE) documentation:

…might indicate that WCF is not correctly configured.

To resolve the WCF issue

• The error returned is a “HTTP Error 404 – Not Found”. This might be due to an issue with the WCF scriptmaps registrations. To solve this issue:
  1. Open a command line console as Administrator
  2. Browse to “%windir%\Microsoft.NET\Framework\v3.0\Windows Communication Foundation\”
  3. Run the command “ServiceModelReg.exe –i”
