Re-enable a disabled Excel Add-in (and other Office Add-ins)

December 30, 2009

Developing add-in for Office (Word, Excel, Project, etc) you may have to stop programs very often during debug sessions.
When you start again Word/Excel/ecc you may accidentaly disable your add-in.
Re-enable it is very easy, just read here: How to: Re-enable an Application-Level Add-in That Has Been Disabled.

Copy&Paste for Office 2007:

To re-enable an add-in that has been hard disabled by Excel 2007, PowerPoint 2007, or Word 2007

  1. In the application, click the Microsoft Office Button.
  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 Items, and then click Go.
  6. Select the add-in and click Enable.

Click Close.

Have a nice reading. ๐Ÿ˜‰
