Behavior:
While executing a GAPI application this error is displayed:
DocuWare.Common.Exceptions.DWRemotingException: SwtichChannelProvider cannot load type DocuWare.Remoting.SSPIChannel.SecurityClientChannelSinkProvider, DocuWare.Remoting.SSPIChannel.64
Solution:
The message is a hint that the needed 64bit GAPI files are not available in the application's directory. Copy these files from the sub folder "x64" of the main GAPI files folder in the directory of your application.
Within the directory "x64" you will also find a description in the file named "Readme GAPI 64bit.txt".
