As of 17 September 2018, the only dependency is .Net 4.5.2. My procedure is to create a new bottle and call it 3CX, install .Net 4.5.2 into that bottle and then install 3CX (using the installer from the PBX "Welcome Email") into the same bottle.
Close the 3CX client and wait for Crossover to see that the install is finished and then open the .3cxconfig file from the "Welcome Email"to configure the client.
We're rebels. We're misfits. But mostly, we're software liberators. And we're very, very good at what we do. We have to be. Lots of developers work with open source, but only a tiny fraction of those are good enough to get software that was designed for one platform to work on another one. We invented CrossOver software - a unique approach to cross-platform compatibility that does not require dual-boot or another OS license. We launched PortJump to help app and game developers broaden their market beyond Windows® users. And we launched ExecMode to help organizations solve really ugly technical challenges.
