Add / install an addin via the registry

If you need to create an installer for your PPA or PPAM add-in, you'll need to have it carry out a few simple steps:

Copy the PPA/PPAM file (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). If your add-in will write to any files (config/ini for example), be sure to choose an installation folder that the user will have read/write privileges to.

Create registry entries that tell PowerPoint to load the add-in at startup and where to find the add-in's PPA/PPAM file:

Create this key:


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.

There doesn't seem to be any harm in creating all of these keys if you want to create an installer for any version of Office the user might have.

And under this key (or keys), create these values:

AutoLoad, Reg_DWORD, ffffffff hex
Path, Reg_SZ, Full path to your PPA/PPAM file

Once you do this, PowerPoint will automatically load your add-in at startup and in most cases, will bypass any security warnings that your users would normally see when trying to install an add-in.
