What kind of motherboard or graphics card do you have?
I had all sorts of problems with installing this "product" of Microsoft. I was spitting acid after I learned that my computer would not run CFS 3. It runs FS2002 and FS 2004 just fine but CFS3 was a no-go.
The problem was that I had a Celeron processor that Microsoft in their infinite wisdom left out of the planning process for the game. It totally would not work in the out of the box format. They royally screwed up. They knew it and even the CFS 3.1 patch still won't work.
Intel got to steppin' on the problem and released this update:
http://support.intel.com/support/graphics/intel810/sb/cs-004790-prd798.htmI personally don't care for the game, even playing it on a friends Alienware p4 with a gig or ram and a latest-greatest video card, all the bells and whistles still cannot hold a candle to good ol' CFS 1.
There should be a big label on the CFS 3 box that reads:
"This game probably will make you pull your hair out trying to install it and tweak it. You will also need to download all sorts of patches that are buried deep on our corporate website."
Don't rely on Microsoft to fix your problem, they make problems...they don't fix them. They'll tell you to update your drivers and say a prayer.
IL-2 never had these problems. CFS3 is like a cheap knockoff.
I'm not bagging on Microsoft, I like FS 2002 and CFS1...jury is still out on FS 2004, but CFS 3 sucks.
