Click theUpdatebutton and wait until the process finishes. If you keep your program up to date, then update process will go quickly, because patches usually take no more than 1 Mb.
Important! When you use both desktop and web versions, upon releasing of a new update your version of web-application will be immediately updated. This means that desktop version will stop working until you update it as well. This happens because database version is increased with each release, and application may work only when application version and database version are identical.
