How to: Re-enable an Application-Level Add-in That Has Been Disabled

Microsoft Office applications can disable add-ins that behave unexpectedly while they are being loaded. If an application does not load your add-in when you try to debug it, the application might have hard disabled or soft disabled your add-in.

There are different processes for re-enabling add-ins, depending on the application.

Hard-Disabled Add-ins

Hard disabling occurs when user code that runs while the add-in is loaded causes the application to close unexpectedly, and when you stop the debugger while the constructor or the Startup event handler is executing.

To re-enable an add-in that has been hard disabled by a Microsoft Office 2003 application

  1. On the Help menu, click About Microsoft Office <ApplicationName>.

  2. Click Disabled Items.

    Add-ins created with Visual Studio Tools for Office appear in the list of disabled items as "Addin:<add-in name>AddinLoader.dll"

  3. Select the add-in and click Enable.

  2. Click the <ApplicationName> Options button.

  3. In the categories pane, click Add-ins.

  4. In the details pane, locate the add-in in the Disabled Application Add-ins list.

    The Name column specifies the name of the assembly, and the Location column specifies the full path of the application manifest.

  5. In the Manage box, click Disabled Add-ins, and then click Go.

  6. Select the add-in and click Enable.

  7. Click Close.

  4. In the Manage box, click Disabled Add-ins, and then click Go.

  5. Select the add-in and click Enable.

  6. Click Close.

Soft-Disabled Add-ins

Soft disabling occurs when an add-in throws an unhandled exception in the constructor or the Startup event handler, but the application does not unexpectedly close.

NoteNote

When you re-enable a soft-disabled add-in, the application immediately attempts to load the add-in. If the problem that initially caused the application to soft disable the add-in has not been fixed, the application will soft disable the add-in again.

  1. On the Tools menu, click Options.

  2. On the Other tab, click Advanced Options.

  3. Click COM Add-Ins.
