I don't understand what You mean with "Install beta patch"... these are beta installers that KL usually deliver every 1 or 2 weeks during a beta testing period... once reports of bugs are reported, They deliver new beta installers, there are no beta patches... You have to uninstall the currently beta version and install the new one.
Patches in general are only for official products... They also have their beta testing period, but this time are delivered via KL standard updates/servers...
