Because I had some free time on my hand I decided to do a full reinstall of FSX and my addons, so I uninstalled everything. After that I went into the Winsxs folder to delete the Simconnect entries, which only worked after taking ownership of the folders and giving my account full control. Then I began installing FSX. I ran the sim once, activated it and shut it down. Next I installed FSX Acceleration. I ran the sim once more to activate Acceleration and closed the sim. Then I installed the Cub, Accusim, update 1.1 and the hotfix.
So all's well now, I thought and fired up FSX with the default flight. I only changed the airport to be able to start on the ground. But to my utter surprise I still got the Simconnect error after changing aircraft to the Cub
I'd surely appreciate some more advice on getting rid of this error.
