IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.
When you load a Microsoft PowerPoint add-in by using the Add-Ins dialog box, the add-in remains loaded until you exit PowerPoint. However, PowerPoint does not automatically load that add-in every time you start PowerPoint.
This article describes several ways you can create registry entries for a PowerPoint add-in or wizard so that it loads automatically when you start PowerPoint.

Method 1: Use the AutoLoad Property to Register the Add-in in HKEY_CURRENT_USER
Sub Auto_Open()
' Get a reference to your add-in.
With Addins(Addins.Count)
' Create the registry key in HKEY_CURRENT_USER.
.Registered = msoTrue
' Set the AutoLoad value in the registry.
.AutoLoad = msoTrue
' Makes sure that the add-in is loaded.
.Loaded = msoTrue
End With
End Sub
The RegisterAddin() function adds the appropriate registry entries for an add-in.

' FUNCTION:
' RegisterAddin()
'
' PURPOSE:
' The function registers an add-in in the registry.
'
' ARGUMENTS:
' strBranch - This is the branch of the registry in which you
' want to register the PowerPoint add-in. This value can be LOCAL
' or L(for HKEY_LOCAL_MACHINE) or CURRENT or C ' (for
'
' strAddinName - This is the name of your add-in.
'
' strAddinPath - This is the full path to your add-in.
'
' fAutoLoad - This is a boolean value you can use to set the
' AutoLoad property. If you specify TRUE, your add-in
' automatically loads every time PowerPoint is started.
'
' RETURNS:
' True - If the function worked.
' False - If the function failed for any reason.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.
For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).
You can use a registration (.reg) file rather than code to register your add-in. The following sample text can be used to register an add-in
REGEDIT4
[<key>\Software\Microsoft\Office\8.0\PowerPoint\AddIns\MyAddin]
"Path"="C:\\PPA_PATH\\MYADDIN.PPA"
"AutoLoad"=dword:ffffffff
You can open the registry and add the entries for your add-in by hand. For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).
