Problem

The thinkcell add-in suddenly disappeared in PowerPoint or Excel. In many cases, this is caused by a previous crash of Microsoft Office.

Solution

Windows:

  1. Open PowerPoint or Excel.
  2. Select File > Options > Add-Ins.

  3. The thinkcell COM Add-in has to be available in the Active Application Add-ins list of both PowerPoint and Excel. If this is the case, please refer to KB0004 for other solutions.

    If thinkcell is listed in another section, you can reactivate it:

    1. Choose COM Add-ins in the Manage: dropdown box at the bottom of the dialog > Go…
    2. Tick thinkcell in the COM Add-ins dialog > OK.

    Disabled Application Add-ins Read more

    1. Choose Disabled Items in the Manage: dropdown box at the bottom of the dialog > Go…
    2. Select thinkcell in the list of disabled items > Enable.

    Note: In Excel, the separate thinkcell Excel Add-in may be listed in the Inactive Application Add-ins list. This is okay, because it will be loaded when needed.

  4. Restart PowerPoint or Excel and see if the problem is solved.

Mac

  1. To enable thinkcell again in PowerPoint or Excel, go to the PowerPoint or Excel Toolbar > Tools > PowerPoint Add-Ins... [Excel Add-Ins...] > tick thinkcell > OK.
  2. Quit PowerPoint and Excel: right-click the PowerPoint and Excel icons in the dock and select Quit. Alternatively, open PowerPoint and Excel , then select Cmd⌘+Q.
  3. Reopen PowerPoint or Excel and see if the problem is solved.
