Revit 2012: Error 1406: Could not write value Class to Key

 If you are getting this error:


    Could not write value Class to key\Software\Classes\CLSID

Please open the Regedit and go to:


Then review this post to change the permissions:

NOTE:  Skip Step #1 because you are using CLISID key and you must execute Step #6 in order for the permissions settings to work properly.

Thanks to Martina Foss for confirming this solution and Avto Chachava for pointing me to the location of CLSID.
