I think that I'm gona aking an obvious question, but I'm not able to find the solution to this problem. After creating a project with the Toolbox I am unable to start it. In visual studio. The error in visual studio is: assembly cannot be registered - access denied. Make sure that you run the application as administrator. Access to the HKEY_CLASSES_ROOT\NOAddin5.Addin registry key is denied.
So I tried to create the registry key manually but as manifest I don't know what to pass, because in the solution there is not the .manifest file.
Your help would be really appreciated.
You need to start Visual Studio as Administrator in order to have write permissions for HKEY_CLASSES_ROOT.
(You can also register the addin per user only without admin privileges with some modifications)
