This version is outdated (Jan 2017) and has no P3D v4 installer as a result. However, with these instuctions for Prepar3D v4 owners it is working:
1) Run "EZDok-2-Setup" as usual
2) Execute configuration tool ("config.exe"), select P3D v3
3) Copy All Files from Updates to C:\Program Files (x86)\EZCA2\
4) Launch "ezlauncher" manually
5) Open EZCA from taskbar
