1) create a new text file "Hello.txt" on the desktop - type some word in and save it 2) zip it into "Hello.zip" - you can use the Windows shell command or 7zip 3) open Calc and insert an OLE Object - create from file choosing the zip file (ie C:\Users\...\Desktop\Hello.zip) - show as icon Then the following warning pops up: " Cannot open file 'Hello.zip' as it is damaged. LibreOffice may attempt to repair the file. The damage could be the result of manipulation or a problem during the file transfer. It is advised not to trust the contents of the repaired document. Macro execution is disabled for this document. Do you want LibreOffice to repair the file?" Whatever answer I may click (yes/no) it ends with I/O general error.
