Troubleshoot PPC add-ins not working

Scenario

Cause

Add-ins are turned off:
Either intentionally or unintentionally, the add-ins might be turned off in Microsoft Office.
Incorrect COM Add-in settings:
The COM Add-ins responsible for PPC functionality might be unmarked, preventing them from loading.
Corrupted or incorrect Load Behavior registry settings:
The system's registry might have incorrect
Load Behavior
values for the PPC add-ins, preventing them from starting automatically.

Solution

Prepare Office Applications:
Close all open Word and Excel documents.
Open a new, blank Word or Excel document.
Check Disabled Items:
Select
File
Options
Add-Ins
.
In the
Manage
dropdown, select
Disabled Items
then select
Go...
.
Review the list for any PPC-related add-ins. If you find any, select them, then select
Enable
OK
.
If there aren't any PPC items listed, select
Close
and proceed to the next step.
Verify COM Add-ins:
Select
File
Options
Add-Ins
.
In the
Manage
dropdown, select
COM Add-Ins
then select
Go...
.
Make sure that all relevant PPC Add-ins are marked. There will typically be up to 5 PPC Add-ins. The critical ones are:
For Word:
PPCWord12
and
PPCWord12Repurpose
For Excel:
PPCExcel12
and
PPCExcel12Repurpose
If the add-ins don't remain marked after you apply the settings, proceed to the next step.
Inspect Registry Load Behavior (Advanced Troubleshooting):
If the COM Add-ins aren't staying marked, it indicates a potential issue with their
Load Behavior
in the Windows Registry.
Open the Registry Editor by entering
regedit
in the Windows search bar and selecting
Enter
.
Go to the following registry paths, depending on whether you're troubleshooting Word or Excel add-ins:
For Word Add-ins:
Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\Word\Addins
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Word\Addins
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Office\Word\Addins
For Excel Add-ins:
Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\Excel\Addins
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Excel\Addins
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Office\Excel\Addins
In these folders, search for entries corresponding to the main PPC add-ins (for example,
PPCWord12
or
PPCExcel12
). If you don't find them in 1 location, check the others.
Select each PPC add-in entry you find.
In the pane, locate the
LoadBehavior
value.
Make sure the
LoadBehavior
is set to
3
. This value indicates that the add-in should load automatically at startup.
If
LoadBehavior
isn't
3
, double select it and change the
Value data
to
3
. Select
OK
when you're done.
