I successfully downloaded and installed and flew the Hellenic Air Force livery, as it was a manual install, but on two other liveries it instructed to place the folders in the variants folder then open ACE and install them into FSX with it.

When I'd try to add them it kept saying that it couldn't locate their cfg, files.

Although when I clicked on the variant and before clicking add the thumbnail would show.

I'll have to find a help section for installing variants in ACE I guess.

Thanks for the help.
