    Hi, james

    Those hexadecimal values are crash addresses, not Windows error codes, so they do not identify the cause by themselves. A genuine 16-bit executable cannot run directly on 64-bit Windows; however, the game may only have a 16-bit launcher while its main executable is 32-bit.

    Here are some suggestions you can try:

    Open the game disc or installation folder and look for another executable, such as GAME.EXE, WINGAME.EXE, or a file inside a BIN folder. Try that file instead of SETUP.EXE or the old launcher.

    Use 7-Zip to open the installer as an archive. If it opens, extract everything to a new folder and try the main game executable. Then open its Properties > Compatibility, select an older Windows compatibility mode, and enable Run as administrator. Compatibility mode helps only when the extracted game itself is 32-bit.

    Search the game’s exact title for an official patch, source port, remaster, or modern release from the publisher, GOG, or Steam. This is usually the cleanest non-emulator option because the executable has been rebuilt for current Windows.

    Thank you for your patience in reading, I hope this information has been helpful to you.

    16-bit programs do not run natively on 64-bit versions of Windows. WOW64 does not support 16-bit applications, including old installers and MS-DOS programs.

    Without using an emulator, the supported options are:

    1. If the PC is running 64-bit Windows:
      • Install and run the game on a 32-bit version of Windows.
      • If both 32-bit and 64-bit Windows are needed on the same PC, use a dual-boot setup.
      • Important: the 32-bit Windows installation must be on a separate disk volume or separate physical hard disk. Installing both on the same disk volume can cause the computer to stop responding.
    2. If the game is a 32-bit game with a 16-bit InstallShield installer:
      • Install the 16-bit InstallShield Support package first, then launch the installer.
      • This only helps when the installer is 16-bit but the actual app is 32-bit.
    3. If the PC is running 32-bit Windows 10:
      • NTVDM can be enabled, which provides 16-bit app support on Windows 10 32-bit only.
      • Run PowerShell ISE as administrator and use:
        • Enable: DISM /online /enable-feature /all /featurename:NTVDM
        • Disable: DISM /online /disable-feature /featurename:NTVDM
      • This requires local administrator privileges.
    4. If the game still depends on 16-bit components:
      • It must be updated or replaced with a version compatible with x64-based Windows.
      • If a program requires 16-bit components, it cannot run on x64-based Windows.

    The error values listed do not change the core limitation: on modern 64-bit Windows, 16-bit games are not supported natively.
