Thanks a lot for your answer. I now can try to install the patch. But at all it doesn´t work. I specify the file as input and on the second page folder "WICED" as destination. But alway "get file does not exist". I am using Windows SDK. Could this cause the problem ?
The path is the standard path of the SDK Installation (C:/Users/myname/Documents/WICED/WICED-SDK-3.1.2/WICED-SDK/...) and i renamed the patch file to a.patch. ??? What can i do ?
