I'm hung up on a "Error: The tool was unable to install Application Server Role, Web Server (IIS) Role." error (as shown in the install log).
So far, I've run across a couple supposed fixes (they don't work for me). Microsoft's site lists a KB that needs to be installed (and also some PowerShell to run). Other sites have a policy modification to get updates from MS directly (bypassing WSUS). Unfortunately, none of these seem to make any difference. What else should I try?
