    Solution. You must uninstall Windows Update:

     

    Windows7/2008              - KB4041681, KB4041678
    Windows 10                       - KB4041676
    Windows 2012                  - KB4041693, KB4041687

     

    or:

     

    1. Find prior version (4.0.9801.0) of msexcl40.dll.
    2. Place in another directory. They suggest the application directory, but since in the next step you will modify registry to point to this older version, it can probably go anywhere.
    3. Update registry key HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Jet\4.0\Engines\Excel\win32 to point to the location from step 2.

    What happens if you try opening that workbook from outside of TestComplete?  Any dialogs come up?

        Translate the dialog for me... there's verbage there that I don't understand.  That might shed some light as to what's going on.

         

        Also... what changed... it was working fine yesterday, not today... something changed.
