IF anyone from KE is monitoring this, I also just tried to install the G5 upgrade. The install looked like it went well and I even installed the DirectX9 for good measure (even though I already had it installed).
If I hit LauncherG5 I get an error box that states ''KEError 21051: Unknown Product Code''.
If I go directly to Realflight.exe the error box says ''KEError 92994: Serial Numbers are invalid or missing. You must run the RealFlight Launcher and enter them before RealFlight will run''. Of course, if Launcher won't run, I can't input the S/N.
I uninstalled and reinstalled it once. My PC is fairly recent (Dell with Pentium DuoCore processor, 2.13 GHz and 2GB RAM. Video card is a NVIDIA GeForce 7900 GS with 256 MB.
