Yesterday I faced an issue at one of my customers when installing CM12 in a lab environment. I wanted to install the Application Catalog Website Point Role .

Scenario :

  • My CM12 site is installed and running
  • I am adding the necessary roles such as Fallback status point , Application Catalog website point and the Application Web Service Point.

To do that I added in IIS the component as stated in the prerequisites here :


Then I added the necessary roles and after looking in the appropriate log file , I discovered an error : “ Error: IIS is NOT registered . Setup failed – Error 126. “


To solve this , you will need to navigate to "%systemroot%\Microsoft.NET\Framework\v.4.0\” and run “aspnet_regiis.exe –i “

Make sure that you register the latest version of framework . In this case it is would be version 4 of dot net framework.


After restarting the CM12 services , the role reinstalled correctly without any issues .

Hope it Helps ,
