Autodesk Revit Architecture

[#1]

I'm experiencing exactly the same error! I have been searching the net for ages but no solution yet. I also contact our Autodesk supplier, but they have given me the same "solutions" as I found on the net and Alan posted here...

Can anyone help me with this issue, please?

Hello Alan, Thanks for the FTP access.  I've uploaded the contents of the %temp% folder (after the failed install)

Alan many thanks for sticking with us and sending the information from the server lead.  As the installer ultimately failed because there was no default web site in IIS, here's how I recreated the "default web site" in IIS:

I was able to reconstruct the "Default Web Site" by adding the following lines into the C:\Windows\System32\inetsrv\config\applicationsHost.config file. This xml file hold the configuration information for IIS 7.x management console. It was missing the information for the Default Web Site.  The code block I added back is located in the <system.applicationHost> section.
 
  <system.applicationHost>
    ...
       <sites>
            <site name="Default Web site" id="1" serverAutoStart="true">
                <application path="/">
                        <virtualDirectory path="/" physicalPath="%SystemDrive%\inetpub\wwwroot" />
                </application>
                <bindings>
                        <binding protocol="http" bindingInformation="*:80:" />
                </bindings>
            </site>
             <siteDefaults>
                <logFile logFormat="W3C" directory="%SystemDrive%\inetpub\logs\LogFiles" />
                <traceFailedRequestsLogging directory="%SystemDrive%\inetpub\logs\FailedReqLogFiles" />
            </siteDefaults>
            <applicationDefaults applicationPool="DefaultAppPool" />
            <virtualDirectoryDefaults allowSubDirConfig="true" />
        </sites>
   ...
   </system.applicationHost>

Restart IIS 7 after making the change.

I got the same problem an same error, however my problem already fixed.

From my installation process, it will show "internal information services connection failed" which actually cause by missing IIS role services "managemnet tools". When all options under management tools are installed, installation success without and error.
