I recently installed another Steam Game on my computer, on a different HDD than FSX-SE and now when I open FSX, it does not recognize FSUIPC.dll, or other dll files in the FSUIPC folder (Ifly.dll).  I really have no idea what to do to correct this problem.  I have uninstalled the other Steam game, but no joy.  Any help would be greatly appreciated.  Thank you

You make to re install fsuipc so it can both sim
