I would like to create a Passolo Addin, however i run into some trouble at the very beginning. So i would like to build and try one of your sample add-in (DnContectViewer). First of VS said that the reference assemblies (Pass.Addin.Core and Framework) target .NET Framework 4.6, so i have to change the sample project target framework from 4.0 to 4.6 (just for info). Then i could succesffuly build the sample, however when i manually add it to Passolo, i get this message "The add-in has another interface version". 

After that i removed the two passolo reference and re-add them from the Passolo's installer folder, however the error messages keep popping up. Could you please help me, what i did wrong or what's the problem with the sample app?

This is the config:

This is the output folder:

Finally passolo with the message:
