Dennis - my checklist is for FS9. Sorry - I didn't make that clear in my earlier post. I haven't tried it with FSX. > First of all, is the Network Interface that you > refer to commonly know as IvAi? No. The network interface is their name for the PC running FSX > Second, I don't see anything titled > User Interface in the Start/All Programs list under IVAO. The user Interface is the PC on which you want to run IVap. > Thirdly, > have you come across a manual detailing the multi-PC installation > in FSX? No - but I haven't looked. The FS9 routine i worked out for myself after reading the official manual and a few false starts.
