Free flight simulators can be downloaded on line at various websites such as softonic, flightgear and gefs-online. These simulators will be pretty basic.
You should not download illegaly.
Flightgear is an open source flight simulator you can download. Likewise, Google Earth provides a free flight simulator with choice of two aircraft: F-16 and SR22. The only good online in-browser flight sim I have seen so far is a google earth-based flight simulator that uses the google earth plugin. See related links below.
Some free flight simulators include YSFlight, FlightGear, and or Orbiter. Google those names for more information and/or to download. Also, Google Earth comes with a free flight simulator.
You cannot download Microsoft Flight Simulator 2004, you have to buy it.
You can't, you have to buy it.
You have to have a compatible system for the flight simulator 2012. Also, find a website or a CD that has it for free.
you can download one for free at flightgear.org have fun
one possible option is that you go in to Google and type 'free Microsoft ww2 flight simulator'. you can then download the most recent version. there should be one at the bottom on the 1st page that has the URL www.download.com/windows/flight-simulator-games/1921-7544_4-0.HTML. please note this may only be a trial version.
I have found a download for the Embraer 135 for Microsoft Flight Simulator X. I have put the link to the download below this question. To download you must register with the website but registration is free.
There are many websites with flight simulation games online, but if you are looking for a program to download it more likely that you need to pay for them, so I recommend using the free games.
Quite a few flight simulators use Google Earth. An online example of this would be GEFS Online. GEFS is a free online flight simulator, and can only be used via Google Chrome. Another popular simulator is "Microsofts' Flight Simulator." However, one must buy this software.
The Flightgear flight simulator was not created by a single person. It was created by international group of volunteers. It is open source software free to download.
