I found that my automated Excel workbook doesn't work in case an add-in
called pdf-maker is activated. I cound not find a way do disable this add-in
as it doesn't show up in the add-in list (\Tools\Add-ins) but it shows up
within the VBA editor.
The only way to disable it is by way of deinstalling Adobe Acrobat, which is
not a good method since I need Adobe Acrobat. Is there a way to disable the
automatic link of such an add-in that is not shown in the list ?
