Did you read the readme? All the files from the ezb bin folder must be copied to your app bin folder. Also, if you can provide an error message it would be much easier to help you

Hello DJ I did move all the files from the DLL folder to my bin folder and now it works I thought it was only the referenced dll's that were needed. Thank's!

Yeah there we go! It's silly the way visual studio shares projects. The file references are not always carried over. Select the dll files to be included with your build and they will automatically copy when compiling in the future

Eureka I solved the problem. When you use MS visual studio 2013 you have to use net Framework 4.5.1. And fill this suitable framwork in the Properties of the project Target framwork : .NET framwork 4.5.1... Sorry and thank's for your quick reply. blush
