Additional information: Group '' does not exsist.


Recommended Posts

Good morning and Happy New Year!

I am suddenly running into issues with FSUIPC client where I create a new Visual Studio 2015 winforms project in C# and now when I attempt to open a connection I get the exception "Additional Information Group '' does not exist". 

Here is the stack trace:    at FSUIPC.FSUIPCConnection.Process(Byte ClassInstance, IEnumerable`1 GroupNames)
   at FSUIPC.FSUIPCConnection.Process(Byte ClassInstance, String GroupName)
   at FSUIPC.FSUIPCConnection.Process()

   at System.Threading.ThreadHelper.ThreadStart()

I've created projects before and never had a problem with the FSUIPC Client - it's a brilliant piece of work for those of us trying to connect to the sim.

Any help would be most appreciated.

Hi Scott,

I looks like you're trying to process() the default group without any offsets having been declared.

It's a bit difficult to tell without seeing any of your code however.

I've attached the latest version of the DLL for you to try in case there is a bug in the version you have. This is compiled against the .NET 4.0 Runtime.

Can you post some of the code here so I can take a look?
