Zivver Office plugin - Troubleshooting disabled plugins
Introduction
As an administrator, this article explains how to troubleshoot visibility problems with the Zivver Office Plugin in Outlook.
Outlook can disable the Zivver Office Plugin, even when it measures only a small performance decrease. When Outlook disables the plugin, you will not see the Zivver tab in the Outlook ribbon next to Help, nor the Zivver bar when composing an email.
Verify that the Office Plugin is installed in Windows
Make sure that the Office Plugin is installed. If it is not installed, install the newest version. Refer to the Zivver Office Plugin installation manual.
Check if the plugin is always active
Warning
The next steps explain how to modify the registry. If you modify the registry incorrectly, you can cause serious problems. Back up your registry before you continue. You can restore the registry if a problem occurs.
The LoadBehavior value determines whether the plugin is loaded when Outlook starts. The location depends on the installation type you chose: Just me or Everyone.
If you chose Just me, the LoadBehavior is located in one of these keys:
Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\Outlook\Addins\ZivverOfficePlugin.AddinModuleComputer\HKEY_CURRENT_USER\SOFTWARE\Wow6432Node\Microsoft\Office\Outlook\Addins\ZivverOfficePlugin.AddinModule
If you chose Everyone, the LoadBehavior is located in one of these keys:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins\ZivverOfficePlugin.AddinModuleComputer\HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\Outlook\Addins\ZivverOfficePlugin.AddinModule
The most important LoadBehavior values are:
LoadBehavior = 0 (0x00000000)
The plugin is not loaded automatically at Outlook startup.LoadBehavior = 2 (0x00000002)
The plugin is not loaded automatically at Outlook startup. If the user starts the plugin manually and no problems occur, the value changes to ‘3’.LoadBehavior = 3 (0x00000003)
The plugin is loaded automatically at Outlook startup. If any problems occur, the value changes to ‘2’.
Check if users can deactivate the plugin manually
Users cannot deactivate the Zivver Office Plugin manually when this registry key is set. Check if the following String value exists. If the addinlist key is missing, follow the instructions in the Zivver installation manual.

Check that the plugin is not disabled by default
Check if the Zivver Office Plugin is listed under this key. If it is, remove it. If this does not solve the problem, remove the entire key and add it again. Note that this also removes other disabled items from the list.

| Key | Location |

Make sure the plugin is not disabled due to a delay

| Key | Location | Value data |
|---|---|---|
