[Solved]How to install downloaded payload model?

[Walternate]

Thank you so much, but look..

I got : 1 aircraft cfg file,
1 installation icon (CLS A34060), -brown funny looking icon and it has ''.air'' written on it
and one folder named MODEL, with cls_a346.mdl and ''model'' cfg files.

Can you instruct me what to do with those? No JPG picture anywhere? And this -ahould- be good cause I'm doing this specifficaly for the CLS A346, and
it appears that this is just made for it..

Thank you!
