Remember to try before you buy! You can install and test the Pro version before you make the decision. The Pro version is fully functional even without the license except that events from network, Outlook and Google calendars will have text [Unregistered] in front of them.

Upgrade instructions
Close Rainlendar if it is running and run the installer again. The new version can be installed over the current version so uninstallation is not required. Reinstallation does not affect your existing events or settings.

Important: If you are upgrading from 32bit version to a 64bit it is adviced to uninstall the old 32bit version before installing the 64bit version.

Mac OS X:
Close Rainlendar if it is running copy the .app file from the .dmg archive to your Applications folder.

Just close Rainlendar and reinstall the application from the DEB or the archive like described above. If you installed Rainlendar from the DEB package and you are upgrading from the Lite version to the Pro you need to uninstall the Lite version first. This can be done from the Synaptic Package Manager.

Upgrading from Rainlendar 0.22.1:
Rainlendar2 will be installed in a different folder than the previous version (Rainlendar 0.22.1) so it is not necessary to uninstall the old version before you try the new one. Rainlendar2 will allow you to import your old events and tasks when it is started the first time.

When upgrading Rainlendar2 to a newer version the installation does not overwrite your settings or events so is possible to install the new version on top of the old version without uninstalling the old one first. Just make sure Rainlendar2 is not running while you do that.

If you have an older version than 0.22.1 you need to first upgrade to 0.22.1 and use that to export the events either as iCalendar or Rainlendar's ini-format.
