What kind of magic has this ‘MSIMG32.DLL’? Why can’t inno setup delete it?
Edit: this file was just added to {app} using [File] section, at the end of uninstall I get the message “Some elements could not be removed. These can be removed manually.” what is referred to MSIMG32.DLL exactly.
Why should you have this file in your installation set ? This is a Windows image dll ? Remove it from the [Files] section.
