Hi Kraftwerk. Some aircraft are configured to auto-install. Most are not. If you restrict yourself to the auto-installers you are missing out on a lot. Installing files manually is not difficult once you understand the basic principle. May I suggest you take the time to learn. It should only take a few minutes.

I have a lot of experience with guiding newbies through those first few important steps.  I must have helped literally 1,000s of people to get started over the last 5 years. Please visit my Lair & read my Windows Basics article.

Set up your Windows Explorer folder options as shown on the Working with Windows page.

Then download any complete aircraft from the CFS1 section & install it following this tute http://www.simviation.com/acinstall.htm in conjunction with my Aliasing article.
http://www.simviation.com/lair/aliasing1.htm Take the time to read them properly & follow the instructions carefully.

If you still have problems please mail me & tell me the aircraft you wish to install & the page it's posted on. I can then download/install it myself & walk you through it.

There is no reason you cannot do this.

I found the page for the USF Aircraft its
