I just had the same problem. Here is how I fixed it...
Use the run command to run appwiz.xpl
Click on Turn Windows features on or off
Expand World Wide Web Services, Expand Application Development Features, and check the boxes ASP.NET 3.5 and/or ASP>NET 4.6 depending on which version you are targeting.
Restart IIS Server.
Hope this helps.
