Description:
The mysql-excel plugin creates a "excel not installed Warning" if you try to open a excel worksheet/table included in an word file.
The only solution seems to be to remove the add-in.

How to repeat:
MS Office Pro 2010 32bit:

Create wordfile, insert Object - Object - MS Excel Worksheet .... put some numbers in ... then save word file.
Reopen Word file and doubleclick into the table. et voila ...

Suggested fix:
remove mysql for excel sems to be the only solution

Hello   Rico Pietzsch,

Thank you for the bug report.
Verified this behavior on MS Excel & Word 2013.

Thanks,
Chiranjeevi

This problem is caused by any COM Interop add-in, even by Microsoft's PowerPivot.
Found some articles about this:

Attempted to fix this by trying the method of calling Marshal.ReleaseComObject on event handlers but actually the behavior of the add-in was damaged by doing that.
While we keep this add-in developed using COM Interop we won't be able to fix the problem.
