1. Start application
2. Click 'Init' (The Application will now check which patches are available, and make a security backup if your manila. This can take some secoonds)
3. Choose the file you want to change, tick 'Patch' and enter your prefered file. Click on Save.
4. If you want the calendar to start in your favorite view and not in Agendaview, enable patch on calendar.exe an simply remove '$' from arguments. Be sure to set default view in calendar settings to month view as well.

Now, when you click calendar in TF3D it will open in month view instead of day view.
