I have just upgraded the our server from 11 to 12.5 and wanted to use the new 3cx phone on our terminal servers for our users aswell. i installed the 3cx phone on my test server and when i open the welcome mail with .3cxconfig under my admin account all goes well. When i than log in with a user account and open that .3cxconfig the program wants to open the 3CXPhoneforWindows125.msi again and install again. If i allow this in the applocker than it even asks to reboot the server again. And even allows the user to do this. However when i save the .3cxconfig to the desktop, and drag the config on the running program the config does get loaded. So my question is? why does double clicking on the .3cxconfig file starts the whole installation again for each new user. The program is already installed it should only load some settings.
