Hi Ahmet.

Go to http://www.prepar3d.com/ and read up on it. Eventually you will get to the pricing page. I'll give them to you here though:

So you buy it. Download it (3 files - 2x4GB 1x2GB, so about 10GB). Install it. It's that simple

Full license $US199.00
Academic License $49.95
Developer $US9.95 per month subscription

Lockheed Martin bought the Microsoft® ESP™ technology, which basically means they bought FSX from Microsoft, and are continually updating/improving it. I like it a lot, and I find it a lot more stable than FSX and I also get a better performance than FSX (that was with v1.3). 1.4 was released, I installed it yesterday and tested it today, I can't say how much better 1.4 is over 1.3 because I just upgraded my computer on Wednesday. It is STILL better than FSX, but the test will be if I use the Side By Side licensing on my Orbx FTX addon scenery.

Here is a quote about how it began:

In November 2010, Lockheed Martin debuted Prepar3D 1.0, based on Microsoft® ESP™ technology, as a training application for military, educational, civil and aviation professionals
