I am installing 3CX on a 64 bit windows 7 computer. The client installs okay but it does not launch. Both Visual C++ 2010 and 2015 have been successfully installed. I have checked the 3CX Phone log and I can see the following error: System.IO.FileNotFoundException: Could not load file or assembly 'VCEWindows8Agent.dll' or one of its dependencies I have tried uninstalling 3CX, rebooting the laptop and installing 3CX again but the issue still persists. Does anyone have a solution for this issue?
