Introduction
3CX recently released Update 6 of v15.5 including major SSL security updates and great new features within the web client and smartphone apps.
Due to the importance of this update, those using the IP PBX can update to this service pack regardless of whether they have 3CX maintenance.
Users of older IP PBX versions (15.0 and 15.5 users) are now able to update with ease thanks to tools prepared by 3CX.

After you have extracted the downloaded file, right click the file “3CX WinUpdater.exe” and select Run as Administrator.
Note: Your 3CX services will stop and start multiple times and timing will depend on how many service packs need to be installed.
You will see the window below as the PBX is updating, keep this open.
