Alternatively, close all respective processes in the Windows Task Manager.

  1. Open the Windows Task Manager and check for remaining POWERPNT.EXE or EXCEL.EXE processes.

Is there a think-cell group on the Insert tab of Excel's ribbon? If so, try think-cell's built-in repair mechanism to enable it in PowerPoint, too:
