Ok the CoCoL.dll file was not present in the Duplicati 2 program folder. I got a clue from this thread:

I uninstalled 2.0.2.15 and then reinstalled it clean. Now the CoCoL.dll file is there and it starts properly.  
The in-place upgrade over 2.0.2.1 to 2.0.2.15 failed to install the dll.

You guys might need to look into the installer logic a bit more.

Thanks!
