Hi-jacking this a little but having the same issue with ACE not opening. Program "opens" on the taskbar and if i hover over the icon i see a small window above the icon with a dash color in the middle. At no time do i see the program open.

Tried running ACE as administrator.

Tried copying prepar3d.exe to fsx.exe

Cleared registry of all captain sim products that i could find.

Cleared all folders related to captain sim.

I have downloaded 777 again with new links, installed as administrator.

The 777 works great in prepar3d v3 but the ACE is the issue.

Running windows 7 64 bit
Intel i5
8Gb Ram
GTX960

Can't think of anything else, but any ideas on what i can try next?

Thanks,

Andrew
