Running the latest 2.1.413.111 on Windows 7 64-bit, brand new OS install with all updates.
The only Boxcryptor context menu items I see are "open in boxcryptor" and "show in boxcryptor". I do not see the "-> encrypt" option when right clicking on file or folder. I've tried adding a folder in Boxcryptor (unlimited personal license). I've reinstalled, repaired, remove and install new, and rebooted between each step. Still no context menu.
