Enable or Disable Excel Add-in

Hi Guys!

I need to enable or disable a few add-in in excel, there is a way to do it without going to the long path, I mean without open excel and going to options?

I will appreciate any thoughts

You could use the RegistryKey class to modify registry and control the add-ins.

Below code will enable and add-in for you.

RegistryKey myKey = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Office\Excel\Addins\Create.ExcelAddIn", true);
if (myKey != null)
{
    myKey.SetValue("LoadBehavior", "3", RegistryValueKind.DWord);
    myKey.Close();
}
