Unable to export .tiff file

I am trying to export image file from excel using XL Toolbox. But it is showing the following error

An error occurred during export.

The following error message was received:

Unable to cast COM object of type ‘System._ComObject’ to interface type ‘Microsoft.Office.Interop.Excel._Application’. This operation failed because the Querylnterface call on the COM component for the interface with IID ‘{1000208D5-0000-0000- C000-0000000000461}’ failed due to the following error: Library no registered. (Exception from HRESULT: Ox8002801D (TYPE_E_LIBNOTREGISTERED)).

Could you send me a log file? Enable logging in the Preferences. Send it to me via PM here on the forum, or directly to daniel@xltoolbox.net.

Could you please tell me where I can get the log file?
