    Default Install Reinstall steps FSX boxed edition (Gold)

    Recently hard drive crashed and it took me days to gather all the info and about 7 reinstalls to finally find a method that works. This works for me now twice-no problem. It is for FSX plus Acceleration Gold boxed edition. May tweak for others.

    FSX REINSTALLATION of Gold Edition out of the box with Product Keys.
    a. UNINSTALL Acceleration from the Apps/uninstall on computer
    b. UNINSTALL FSX from computer apps or from the disc 1.
    c. CLOSE/REOPEN Program Uninstall and make sure all FSX components are gone.
    d. Go to C:\Program Files (86x)\Microsoft Games\ Microsoft Flight Simulator and delete this folder or whatever drive you had it on.
    e. Go to C:\Users\YOUR NAME and delete any fsx material. OF COURSE SAVE in another folder all FSX stuff you want to put back in later!
    2. Reset the license key (Cause of Error 1603)
    a. Make sure MSKB928080 is installed to C: drive root folder. You can download it from the web (but not Microsoft of course)
    b. Run the following as administrator
    b. Open cmd prompt from start menu and "run as administrator"
    c. Type "cd C:\ " then hit enter (NO QUOTES. I'm putting those in to clarify what to type. No quotes unless I say to put them in.)
    d. Type cd MicrosoftKB928080 and hit enter
    e. Type "resetsldl -All " and hit enter. NOTE: there is a space between ldl and -
    Should get message that success in token store reset.
    3. Reset Windows Installer (Cause of Error 1722)
    a. Click Start, Click Run and type “Services.msc” (without quotes) and press Enter.
    b. Double-click Windows Installer.
    c. Set the Startup type of Windows Installer to Manual.
    d. Click Start to start the service. Note down the error message if any. Click OK.
    ((Method 2 [I never had to use this]: Reregister the Windows Installer. Follow these steps for the same.
    a. Quit all Windows programs.
    b. Click Start, All Programs, Accessories and click Run. Type “msiexec /unregister” (without quotes) in the Open box, and then click OK.
    c. Click Start, All Programs, Accessories and click Run. Type “msiexec /regserver” (without quotes) in the Open box, and then click OK. Restart your computer. ))

    3. Install FSX to D:\FSX (a NEW folder completely) where D=whatever drive you will use. Create the new folder. DON"T install to Program x86 folder.
    Place FSX install CD in drive and open\run the setup as Administrator
    After Disc 2 complete, start FSX. I initiated the default flight to make sure it worked.
    4. Close FSX and REBOOT computer
    5. Go to FSX folder you just installed, right click Properties/ security and allow all permissions. I included the "Users" category.
    6. REBOOT computer
    7. Open as Administrator
    8. In START \RUN\Services.msc\Windows Installer Start it again if not running (as above)
    9. Install FSX Acceleration. It already contains SP1 and SP2 so don't have to download/ install those
    10. ERROR CODE 1-80004005 comes up on starting FSX. If you click "Yes to online query", it starts up, but only gives you the trial version.
    To Fix, you have to change the registry.
    Registry Disclaimer:

    EASIEST METHOD to back up: Create a System Restore Point before going any further
    NEXT, edit the registry:
    a. Click Start and type regedit in the search bar and press enter.
    b. Browse to the following location:
    c. Find Upperfilters listed under it, and check its value, if its 0 change it to PartMgr and click OK. Mine said partmgr (lower case) so I switched it to PartMgr
    d. Restart FSX. Should get Activation screen. Choose "Activate Now" and enter Product Key.
    Close, reboot, and restart FSX to be safe.

    Hello and thanks for this information all in one place. I had to reformat my system recently to get MSFS2020 to reinstall. (but that is another story!) The upshot of that was that I had to reinstall FSX and FS9 too. I also used the FSX Gold Edition with the Acceleration Pack. I had to reset the licence key with the reset tool, tricky to do but I got it in the end. Then the Acceleration Pack with the registry fix.
    Apparently this is a Windows 10 issue as I never had to do these steps using Windows XP. Good to have all this info together, happy flying.

    I have never succeeded in a reinstall of FSX Gold, on the same (Windows 7) system where first installed, once I installed the download for Microsoft Flight. Authentication is the issue, FSX starts up in trial mode, asks me to go to authentication, where it fails. Ultimately I went to FSX Steam Edition, which has its own quirks, but installs on Windows 10, with few troubles, at least for me.

    My first experience with FSX was Widows 7, never tried it on XP. On XP (and my first Windows 7 machines) FS9 was my flight simulator choice.

    • class
    • find the string:
    and double click on it.
    • Go to the right: upper filters and double click on it
    • a screen opens on the left and value data should read: written like this:
    PartMgr (so 2x a capital letter)
