I am on Ubuntu 16.04 and I have installed MS Office 2010 over 2010 POL (v4.2.10 with Wine 2.22). The icons locked to the Unity Launcher are the correct MS Excel and Word icons, and both Excel and Word works fine when I click those icons.
Here's the Excel .desktop file
[Desktop Entry] Encoding=UTF-8 Name=Microsoft Excel 2010 Comment=PlayOnLinux Type=Application Exec=/usr/share/playonlinux/playonlinux --run "Microsoft Excel 2010" %F Icon=/home/jd/.PlayOnLinux//icones/full_size/Microsoft Excel 2010 Name[fr_FR]=Microsoft Excel 2010 StartupWMClass=EXCEL.EXE Categories=Office;Spreadsheet;
How can I change this behaviour to enable the Excel instances to be grouped under the Excel icon and the Word instances under the Word icon?
