Hello, I’ve developed a black box with C#. Until today, it has worked with no problem using FSUIPC in FS9 & FSX. My application uses the FSUIPCClient.dll reference version 2.4.0.0. Today, one of my users has updated FSUIPC4 to 4.934 (FSX). Now it’s impossible stablish a connection between the application and FSX. FSUIPC throws an exception (when trying to connect) with error #7: “Error #7: FSUIPC_ERR_VERSION. Incorrect version of FSUIPC” I’ve searched a new version of FSUIPCClient according to FSUIPC 4.934 but with no result. I hope you can help me, Regards, Daniel
