I copied it from this path
"C:\Windows\WinSxS\Fusion\x86_microsoft.flightsimulator.simconnect_67c7c14424d61b5b_none_7a98ffdea9fe1e16"
directly in to "C:\Microsoft Simulator X"
It has only partially solved the problem as, when I tried to reinstall the F-18 Superbug it came with simconnect error again. I suspect the only sure way to fix this would be to move that whole x86.... folder directly into the WinSxS folder; however, as that is a systems folder I'll need administrative rights, which I will be looking at next.
