I have had FSX installed now close to a year. I'm using FSX Deluxe and installed all SP's and Acceleration. I am using Vista 64 and have PMDG. Super80, some addon scenery, UTX, UT Traffic, FEX, ActiveSky, MyTrafficX and other addons. I have never bothered with SDK, even though I installed it with FSX and also the Updates for it. It has come to my knowledge that I should have some access to SDK functions from the FSX Menu - which I don't. There are no menu items from within FSX and neither in Windows. Is this correct or need I install FSX all over again?ThanksWilbertAbit AW9D-MaxThermaltake W0106 700W PSUIntel QX6700 QuadcoreVista Ultimate 644x1G Ballistix Tracer (PC2 8500)2x150GB SATA WD Raptor - Non Raid2x320GB SATA WD SE16 - Non Raid2x IDE Light-On DVDRW 165H65BFG 8800GTX OC2 768MB 626MHz Core Clock - nvidia 169.253x SILENX 120X25MM FANS + 2x 10in XCLIO Wind Tunnel Case FansDanger Den Water CoolingEnermax temp/fan controller

- Update the SDK with the one on the Acceleration DVD- Activate the plugins from your %APPDATA%MicrosoftFSX folder (just paste this in the addressbar)- In this folder there's a dll.xml file- In this file change all the: Trueentries to: FalseDaniel

Thanks for the replay but that did not help. I have wiped out my drive C and D (where FSX is installed) and reinstall everything all over (Vista Ultimate 64 & FSX and all upadates) - still no go with Addon Menu.Any more suggestions?Thanks,Wilbert

In the dll.xml file, did you change the path entries to match those of your SDK install?Regards,Jim Karn

I think this is the definitive Wiki on ensuring a successful implementation of the SDK installation:http://www.fsdeveloper.com/wiki/index.php?...ation_%28FSX%29Should help you get over the bumps.Cheers,Kevin
