Hi,I understand that ASV 6.5 is OK with FSUIPC 3.7 on FS9. When I upgrade to FSX I understand the need to go to ASV 6.5 and FSUIPC 4.0.Also, my question does not concern the obvious benefits of adding Ground Environment Pro. Could you tell me what does ASV 6.5 do beyond what version 6 does in FS9? Does it add anything or fix anything for FS9? Or is there no change as far as FS9 is concerned? I think that ASV is a great weather program.Thanks!Davidl3541

Hi David,Thanks for the question. 6.5 adds compatibility for FSX. It doesn't do anything for FS9 at this time.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/
