Now bear with me, I've only been using MSFS for 20 years, so I'm still kind of new at it....LOL.I have been trying to get the SDK to become available in the sim to try and build a mission. I still cannot get the tools tab to show. I've been to every FS website that has mission building sections, and it looks like I'm doing everything right, but still no tools tab.I have the deluxe edition of FSX. I downloaded the SP1a download for the SDK.Is this the sequence?Install SDK from discRun SDK configureInstall SP1aRun SDK configure againModify dll.exe file for pathAt this point, I just uninstalled the SDK, and have taken a break for now. Any tips or tricks that I may be missing?Thanks,Tim

Do you have Acelleration, or SP2 installed? If so, you will need the update to the SDK. If you have Acelleration, it is on the Acelleration disk. If you just have SP2, it can be found where you downloaded SP2.Gunner
