ServiceModelReg.exe is used to register WCF and update scriptmaps at the Internet Information Services (IIS) metabase root and for all scriptmaps under the root. Existing scriptmaps of lower versions are upgraded to the current version.

If you have installed .NET FrameWork before Installing IIS, you will need to execute this command manually:

Run Command Prompt as Administrator.

32-bit machines:

64-bit machines:

"%SystemRoot%\Microsoft.NET\Framework64\v3.0\Windows Communication Foundation\ServiceModelReg" -i
