When I click on the update for an aircraft (right side of update window) all I get is a small window with a URl pointing to a zip file. Not knowing what to do with this I tried clicking on it and pasting iit into the browser address search but that just give a bad URL indication. Tried Chrome, Firefox and IE Explorer.

 

Example:

http://www.carenado.com/CarSite/Portal/SiteDownload.php?p3=BE700X_SP2.zip

I had the same problem, so I emailed Carenado through their website. They promptly emailed me back with the file I wanted as an attachment
