Windows 10 & FSX: Steam Edition

Thank you to everyone who got in touch with us about running FSX: SE with Windows 10. It seems a lot of you are having mixed results ranging from everything working fine to nothing working at all.

Windows 10 is a brand new operating system, and like all new OS, a few problems are likely to pop up. Likewise, many graphic and sound card makers are yet to release driver updates which are compatible with Windows 10. Things will get better, however it will take a little time. We understand that this doesn’t stop the situation being any less frustrating for those of you experiencing unexpected problems.

We have compiled a list of possible fixes for those of you having issues running FSX: Steam Edition on Windows 10. While these fixes may solve the majority of problems, we cannot guarantee they will work for everyone.

  1. The first thing we would advise is making sure all of your drivers are up to date. Many modern drivers include an update feature which will check for a new release for you, however it is always worth checking on the websites of people like Intel, NVidia and alike to see what advice they are offering for using Windows 10 with their hardware.

For more information on graphic card driver compatibility with Windows 10, we advise you to contact your graphic card manufacturer for the latest news and updates.

  1. Next, check your Windows settings. In theory, everything should have been carried over from your previous version of Windows, however it is not always the case. Try checking all of the obvious things like your display resolution, mouse, etc.
  1. Now is also a good time to check what else is running on your PC. Even if you have not started to run anything, Windows may launch certain programs upon start up. Please refer to the Windows help files for more information about enabling and disabling programs when Windows starts. The fewer programs you have running, the more memory will be available for Microsoft Flight Simulator X: Steam Edition to use.
  1. Since the launch of Windows 10, Microsoft has released a number of updates to the operating system. We advise that you download and install these, as many players are reporting improvements in running FSX: SE after having done so. For the latest information regarding Windows 10 updates and information about how to install these please click here.
  2. Turn on the Anti-Aliasing option in FSX:SE. To do this, follow these instructions:
  • Go to the Settings tab on the FSX: Steam Edition home page
  • Click on the “Customize” option at the bottom
  • Click to check the “Anti-aliasing” option (see image below)

6. Try running FSX: Steam Edition with or without Windows 8 compatibility mode. To do this, right click on the game’s desktop icon, select “properties”, then look under the compatibility tab. Either way, you will still need to run FSX: Steam Edition as an administrator. You can also find the Windows compatibility trouble-shooter in the control panel. Click on it and follow the instructions on screen.

7. Make sure all of your files are verified through Steam. This enables Steam to compare all the Microsoft Flight Simulator X: Steam Edition files installed on your computer against the ones it believes you should have. If any are missing, Steam will update and download them. In order to complete this procedure, you will need to be connected to the Internet.

Instructions for verifying your game files through Steam are as follows:

  • Load the Steam platform and log into your account
  • Click the Library tab in the menu at the top of the screen
  • Click the List View from the view options on the top right of the screen
  • Right click on Microsoft Flight Simulator X: Steam Edition to bring up a popup menu
  • Click on Properties from the popup menu to bring up another popup box
  • Click on Local files from the popup box menu
  • Click on Verify integrity of game cache from the Local file options
  • Wait for the progress bar to finish verifying your files. Additional files may download
  • Restart Steam
  • Restart Microsoft Flight Simulator X: Steam Edition
  1. Re-install DirectX 9 after installing Windows 10. To do this, click here visit the DX9 website and follow the instructions.
  1. Try running FSX: Steam Edition in borderless windows/windowed mode by toggling ALT+Enter
  1. Reinstall FSX: Steam Edition. Steam provides the ability to reinstall the game to the default system. To perform this reinstallation, you should perform the following steps:
  • Sign out of Steam
  • Backup the disk containing your FSX installation
  • Delete the contents of “<drive:>Program files (x86)SteamSteamAppsCommonFSX” and all subdirectories
  • Log on to Steam
  • Select “View Games Library” from the “Games” menu
  • Right-click the Microsoft Flight Simulator X: Steam Edition icon and select “Properties”
  • Select the “Local Files” tab and click on “Verify Integrity of Games Cache”

We have done extensive testing with all add-ons offered in our Steam store, and can confirm they are all Windows 10 compatible. Unfortunately, we cannot guarantee the compatibility of add-ons not offered via our Steam store. We would highly advise installing just the core simulator, then installing your add-ons one at a time, checking for any possible compatibility issues.

  1. Try reinstalling the Microsoft Visual C++ 2005 Redistributable Packages. FSX: SE requires the Microsoft Visual C++ 2005 Redistributable Packages in order to run. Make sure that you install them to the same hard drive that you have FSX: SE installed on, however you do not have to use the same directory:
  • Locate the following directory on your PC:
  • [your drive]SteamsteamappscommonFSX_CommonRedistvcredist2005
  • In the directory you should find two files called vcredist_x64.exe and vcredist_x86.exe. Run each file one at a time and follow any on screen instructions.
  • Restart your PC and try loading FSX: SE again.
  • If the game still won’t start, click the two links below:

  • Download both of the Microsoft Visual C++ 2005 Redistributable Packages from the Microsoft website.
  • Once downloaded run both of the files from your PC and follow any on screen instructions.
  • Restart your PC and try loading FSX: SE again.

If FSX: Steam Edition is still not working, you may wish to revert to a previous version of Windows. Please note this could adversely affect other programs on your PC.

If you are still having problems, please contact us via our support link and we will try to help you get up and running as quickly as possible:

If you find a solution that works for you or think that you have found the cause of an issue please share it either here or on our Steam forum so your fellow players can learn from your experiences.

As we continue to investigate in the studio, we will keep you updated on any further developments.

Happy flying!

  • No offense to those who are forward thinking, but I’m taking Windows 7 to my grave. Why anyone would eagerly want to update to a new unknown OS, just to absorb all those problems is beyond me. What benefit is there? Don’t fix what ain’t broken, I say.

  • If it wasn’t for those early upgraders, you wouldn’t have had a nice version of Windows 7 to go to. 🙂

    The sooner bugs are fixed, the sooner we’ll have a better OS with new additional features. Adapting/evolving is necessary if you want things to move forward.

  • Well I am having this trouble. I hope you know how to fix it

  • So has anyone asked about FSX running on pc and windows 10?

    • Hi Gpaw,

      Our players have reported mixed results when running FSX: Steam Edition on Windows 10. It works fine for some people, while others are experiencing difficulties, most of which are likely caused by incompatible graphic card drivers.

      I hope this helps!


  • Greetings I have just plugged in a brand new Dell xps desktop with nvidea 970ti.. loads of memory n drive n no clutter. as I haven’t set up a dual screen FSX in a while I’m having trouble with the extend screen option. it seems ( windows 10) outside of FSX but only sometimes inside FSX . When attempting to bring up throttle window or nav comms window sometimes I can pick up n move to dual screen and sometimes not? any suggestions? And any help on 3 screen articles would be great ( one main and 2 for PFD and MFD thans

    • Hi Alan,

      This is a common problem with multiple monitor setups. Microsoft installs its own Nvidia drivers in Windows 10. You will need to download and install the drivers directly from Nvidia rather than use the default ones that came with Windows.

      I hope that helps. If not, please contact our support team here:


  • Just upgraded to Windows 10, bugger! Internet browser (Google) very slow.
    Ran FSX Steam, things getting worse. When I select a Free Flight or Mission get a blank screen (no % count box) until the flight opens.
    When I End a flight, I get a blank screen (not the three options box), – if I press E it will work.
    Tried the solution of going to windows screen ALT+Enter and it now works, but I prefer using the full screen.
    Checked for new drivers for my video card, up to date. Files verified thru Steam.
    Would rather not have to re-install, I have loads of xtra Planes/Airports/Scenery etc.
    Do I have a choice and would a re-install fix the problem?????

    • Hi Tony,

      Thank you for getting in touch. We cannot guarantee a reinstall would definitely fix your problem, however we can offer you personalized support through our Kayako support page at

      I hope this helps!


    • I just found a very simple fix to this.

      If you are getting a black or blank screen when loading to a flight, with no percentaged loading bar, and if you are getting a locked up black screen on trying to exit a flight, or when pressing escape in a flight, do the following.

      Start FSX. Go to Settings and Customize, tick DirectX 10 Preview. Exit FSX, and restart. Go back to Setting and Customize, check your resolution is set and that DirectX 10 Preview is still ticked. Go to a flight.

      You should now see the loading screen, and not get the black screen when pressing Esc in a flight, or when exiting a flight. This is what worked for me. (Also set run as Admin just to be safe)

  • That is very good advice, GamingKen 🙂


  • any body here managed to go DX10 on windows 10 pro
    if so, HOW>?
    I have tried the fixer with no luck.
    please help

  • If you have windows 10 and your FSX will not launch even with the help of the trouble shoot provided on this thread, it is most likely because you have DX10 activated. FSX with DX10 activated on Windows 10 will crash your simulator as soon as you click fly now. I repeat DX10 on FSX running Windows 10 is not compatible..

    • I’m having the exact same problem… anybody out there knows of a fix for this? I sure can fly without issues with the DX10 un-checked, but it doesn’t look as nice, which is kind of disappointing?
      Thanks in advance!

  • O meu FSX-SE com o Win7 está perfeito, pois sempre mantenho o meu PC seguro, faço backups e não instalo qualquer coisa. Posso lhe garantir que enquanto este time estiver ganhando, o windows 10 vai ficar em 2º plano.

  • A few problems on my Windows10 before some updates were made but after all run 100%

    • Good to hear everything is running smoothly for you now, Nuno!

      Happy flying,


      • Hey, spent hours and hours trying to solve a problem I keep getting.I keep receiving this same error message every time I try to install a theme to FSX Steam Edition on the REX 4 application:
        startapplication.startWxEngine()-system.component model.wen32exception (0x80004005):the system cannot find the file specified at System.Diagnostics.Process. Start withshelfexecuteEx(Process Start Info Start Info) at system.diagnostics.process.start () at rextexturedirect_se.functions.startapplication.start WxEngine ()

        All in all, any help here would be great!
