I have AI carriers 2 installed. However. To get it to work, I have to launch FSX, then go find aicarriers.exe, double-click it to launch it, then go back to FSX. Then it appears under the addons menu, and I can run it using the shift-j key command, drop carriers in the water and land on them. This is with my current Windows 7 (64) installation. With the same computer, when I had Vista (64), all I had to do was launch FSX, then hit shift-j to run AI Carriers. I checked the exe.xml file, and AI carriers is in there. Anyone ever seen this one before?
