For me, I have an i5 12450H and the plane works perfectly, works just as well as the Fenix which is a huge plane. As far as the install goes, I bought mine from Asobo, and Asobo has an installer so its just as simple as getting the installer and installing it with a couple clicks there.
If you want timely updates Contrail is a better choice to purchase the plane. Aerosoft is painfully slow on pushing updates. As far as INSTALL goes either sites downloader will complete the install into your Community folder.
Update to this, been a bit. After looking around, the jet has to be one of my best performing airlines along with the 737-800. Even that is good because the 737 is greatly optimized while the E-Jet is beta, so performs great.
