If you are comfortable executing these steps, give this a try:
(0) Run an eMC Backup [ MENU > BACKUP ]
(1) Delete any installation files you have downloaded.
(2) Uninstall eM Client, making sure to NOT delete your database directory when asked. This will ensure your settings and data remain in place.
(3) If it exists, delete C:\Program Files (x86)\eM Client
(4) Download and install the latest version from Release History.
(5) The latest version of eM Client should then start with all your data in place.
