I just installed what I thought was the latest version downloaded from 3CX on 8/27 but after the installation and configuration I see that my current version is 15.0.62928.5 and an update to 15.5.1694.0 is available. When I select the update and allow it to proceed I'm immediately logged out of the web portal but I don't see any activity in the Windows task manager (this is a 2012R2 intallation). I can log back into the web portal and am presented with the update options again as if nothing has happened. I get an exit code of -1 emailed to me with a subject line of "update complete" but nothing has changed. Any ideas?
