How do I install aicarriers on FSX Steam edition.

This should help.

Let us know how you do.

Thank you so much for getting back to me.
I get a message come up that I have java 1.8 installed & need at least java 1.5. I would have thought 1.8 would be OK but it seems it isn't.

That's a shame, if you load new version of Java you get stuck with a load of garbage that comes with it (no opt out).
Check on the Steam Forums to see if others have bothered with Java downloads or have done something else.

Thanks for your help. I will try as suggested.

Good luck, let us know if the Steam Community can help.

No luck, I'm afraid.

See if this helps.
