I am installing Sitefinity 3.7 SP1 on Windows Server 2008 and in Project Manager after choosing a site template, it fails with the following error:
Unable to create the virtual directory: Unknown name. (Exception from HRESULT:0x80020006 (DISP_E_UNKNOWNNAME))
Can you please confirm what the Authentication settings are supposed to be on the \telerik and \telerik\Sitefinity3.7 web sites? I suspect a problem there.
Otherwise, I am looking for troubleshooting tips.
