Hi,just wanted to clear up an issue I have before I attempt to install the AS6.5 upgrade...I am still running FS9, and will be for some time for reasons not worth mentioning here.1. I read over at Pete Dowson's forum that FSUIPC4 is not compatible with FS9, since it incorporats with Simconnect in FSX and cannot interface with FS9 like FSUIPC3.7 does...2. Do I understand correctly that AS6.5 requires FSUIPC4? If so, it cannot work on FS9... Then I do not understand how some in the forum here state that they have installed AS6.5 with FS9...Have I missed something, or is AS6.5 fully functional with FSUIPC3.7?CheersAndrewEDIT: Changed title to avoid misleading other forums users into thinking there is some major problem here...

Hi,Thanks for writing. You need FSUIPC4 in FSX. You can leave the FS04 stuff alone. No, you don't need FSUIPC4 with version AS6.5 so yes AS6.5 will work with FS04 and FSUIPC3.7.Thanks!Jimhttp://www.hifisim.com/Active Sky V6 Development Team Active Sky V6 Proud SupporterHiFi Beta TeamRadar Contact Supporter: http://www.jdtllc.com/AirSource Member: http://www.air-source.us/FSEconomy Member:http://www.fseconomy.com/

Cheers!Thanks for summarising...Time to get that AS6.5 update then...Andrew
