I did try and install QW757, but that was also a addon that required addonmanager.
The QW757 would crash FSX when loading. I also tried loading my ejets emb 172 & 195. The airplane loaded fine, except the gauges were scrambled. Of course I knewthis airplane was SP2, but didn't think of SP2 being corrupt. OH well live and learn. Next person that has a problem with not seeing addonmanger in FSX menu, should maybe try this first.
3rd party module that requires the 10.0.61259.0, which is what we use (it's the latest version used by SP2 and Acceleration). A module requiring an older version (10.0.61637 in this case, which is the one that comes with FSX as shipped) wouldn't be affected by a corruption of the newest one.
I still don't understand why the simconnect folder read 10.0.61259. and the .dll was 10.0.6137. When I reinstalled SP2, It was also 10.0.61259 (folder) and 10.0.6137 (.dll). The only thing I did was, instead of using the previous SP2 that I downloaded. I downloaded the SP2 right threw FSX and saved it to disk, then install. Don't know if that made a difference or maybe the SP2 that I first downloaded got corrupt during download from internet. Well I'm going to check out the GSX trial when I get home, Before purchase.
Thanks again
