Add / install an addin via the registry
If you need to create an installer for your PPA add-in, you'll need to have it carry out a few simple steps:
Copy the PPA (add-in) and any other necessary files to the appropriate folder (which might be one that the installer creates or one that the user chooses or some other folder)
Create registry entries that tell PowerPoint to load the add-in at startup and where to find the add-in's PPA file:
Create this key:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\X.X\PowerPoint\AddIns\ADD-IN-NAME
And under it, create these values:
AutoLoad, Reg_DWORD, ffffffff
Path, Reg_SZ, Full path to your PPA file
Change ADD-IN-NAME to the name of your add-in
Change X.X to the correct version number of the copy of PowerPoint on the computer where you're installing it.
