Just ran into an error this morning while installing the Application Web Catalog role on my ConfigMgr 2012 server. When trying to log on to the catalog I got an IIS error related. I look into the SMSPortalWebSetup.log file on the site server and noticed this Error: IIS Asp.Net is not registered

To fix the error I had to manually registered the component

  1. Open a command prompt as administrator and navigate to C:\Windows\Microsoft.Net\Framework64\v4.0.30319\
  2. type aspnet_regiis –i and Enter

  3. Remove the Application Web catalog role and reinstalled it (not needed but I didn’t want to wait for the reinstall process to kick in)
  4. Now my Application Catalog is installed correctly
