iis express unable to access the iis metabase error

Question

I'm developing an asp.net mvc application using Visual Studio 2015 community. When i tried to configure the application to use the iis express server, it throw the following error :

Unable to access the IIS metabase. You do not have sufficient privilege to access IIS web sites on your machine.

I'v tried all the proposed solutions below but without any success :

1. Check the following registery key : HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Personal, and ensure that it point to a valid directory(Actually %USERPROFILE%\Documents),
2. Taking ownership of %systemroot%\inetsrv\config directory,
3. Run Visual Studio 2015 as administrator,
4. Remove/Install the IISExpress (i have tried all versions :10,8 and 7.5).

Any help about this issues would be very appreciated.

Thanks
