I had a pile of grief getting V12 VAD projects deployed to a V12 3CX, both running on the same machine (Win 7 Pro x64). These mostly revolved around "configuration server not found" and suchlike error messages. I've finally got it to work by uploading not to 127.0.0.1 but to the LAN IP address of the machine, plus changing the confignic entry in the 3cx ini file to 0.0.0.0. What's eluding me, is why? g.
