Hi RajeshV, I don't know why we are not getting any experts to help us on these forums. I am trying to find out info about installing DNN 9 as well, but havent had a response :(
I did find a solution to the problem you mentioned, on this page:
https://stackoverflow.com/questions/9...Since I an using Windows Server 2012 and IIS 8.5, I tried answer #149, and was able to successfully get past this particular error.
I copied the text below. On the page itself you will see a screen shot of the Add Roles and Features wizard. If you are using a different server /IIS version, you might find a different solution on the page.
I hope this helps
Tom
For Windows Server 2012 and IIS 8, the procedure is similar.
The Web Server (IIS) and Application Server should be installed, and you should also have the optional Web Server (IIS) Support under Application Server.
Windows Server 2012 and IIS 8 Requirements for MVC
Just to clarify, the "Web Server (IIS) Support" feature checkbox is not under the 'Application Server' node in the pic above. It will show after you perform several 'next' and pass the Server Roles and Features on the left nav bar and get to 'Role Services' (doesn't appear in the pic above but will appear for you after several 'next'). This drove me crazy :P – thedrs Jun 10 '14 at 16:57
