Hi all there,possibly I ask a stupid question but I'm a newbie with PMDG in FS2004 and I do not know what to do with the FSUIPC module which appears in the task bar of FS.I know FSUIPC from FS2002, but now it is not clear to me: Do i have to register to get all functions?Any help is greatly appreciated.Best regards,Wolfgang

To get all the functions, you need to purchase. However, most commercial products like PMDG will function properly with the free module because these companies have registered their applications with FSUIPC.Bascically, you don't have to do anything with it.

Hello Ken,Thank You very much for the fast answer. Now I will download actual weather and do my first flight with the 737NG in FS2004.Regards,Wolfgang
