The think-cell add-in suddenly disappeared in PowerPoint or Excel.
In many cases, this is caused by a previous crash of Microsoft Office.
Start PowerPoint [Excel].
Click on the Office Button →
PowerPoint Options [Excel Options] → Add-Ins
Office 2010 and later:
Click on File → Options
The think-cell 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.
In case think-cell is listed in another section, you can reactivate it:
Inactive Application Add-ins
Choose COM Add-ins in the Manage: dropdown box at the bottom of the dialog → Go…
Tick think-cell in the COM Add-ins dialog → OK.
Disabled Application Add-ins
Choose Disabled Items in the Manage: dropdown box at the bottom of the dialog → Go…
Select think-cell in the list of disabled items → Enable.
Note: In Excel the separate think-cell Excel Add-in may be listed in the Inactive Application Add-ins
list. This is ok as it will be loaded when needed.
Restart PowerPoint [Excel] and see if the problem is solved.
