Thanks Jeff.I have already fixed my problem, after reinstalling Windows 7.It is a shame that such a good add on has zero customer support from the developer. I clicked on his profile and his last post was on May 19.Hopefully he's gone dark because he is deep into Ezca Ver 2.0Once again, thanks for looking into this.

Strange... That support forum has gone from one extreme to the other. When I first purchased it, his support was second to none - excellent!In the end, I pretty much gave up trying.Thankfully, there are many skilled and helpful folk here that helped me.

If you are thinking of playing around with the winsys folder to fix simmconect, don't even try. This method (and the SDK installation method) worked fine on Windows XP but it will not work in Win7. The only way to fix a bad simconnect dll is to reinstall Windows.

Ramirin - please do not spread tips like this. It is absolutely not the case. You messed up your Windows installation because of inexperience. That's all.I, too am not immune to SimConnect issues, as there are a number of apps that use it: I simply run this quick dos script, and it's fixed - ok?C:CD C:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X SDK\SDK\Core Utilities Kit\SimConnect SDK\libstart SimConnect.msiEXIT

If it's not showing under the Add-on menu that means FSX has not signed this program as trusted, could you check your fsx.cfg if there is ezca under [Trusted] ?

For your information, I did run that script and it did nothing to repair my simconnect.Based on my inexperience you say? I was following advice from Scott of A2A simulations when he suggested I should delete the 3 simconnect folders.If you really think that Win7 is so forgiving when messin' around with its file system, I invite you to delete your simconnect folders and then see if you can have them installed back by simconnect.msi, FSX or a DOS script.
