flyby11 download successfully but not working for windows 11 upgrade

I heard flyby11 is a popular option to let me installing Windows 11 on an unsupported device. I downloaded flyby11 successfully from github. This makes sure I am downloading the legit copy not the variants from other developers.

I followed the instructions and prompts to upgrade my pc from Windows 10 to Windows 11. Unfortunately, the windows 11 setup won't continue after checking the PC. 

Does anyone know a good alternative to flyby11 when is not working as expected?

Thank you

    Best Free Flyby11 Alternative When Flyby11 Not Working

    MediaCreationTool.bat is a free tool that helps you bypass Windows 11 system checks and upgrade directly from Windows 10 to Windows 11 using Microsoft’s official ISO or setup files.

    How it works:

    2. When you run it, it fetches the latest Windows 11 setup files and automatically skips CPU, TPM, and Secure Boot checks.
    3. It can perform an in-place upgrade (keeping your files and apps) or create bootable media for a clean install.

     

    Why it's good

    • Fully transparent, open-source batch file — no hidden binaries.
    • Compatible with most Windows 10 editions.
    • Very lightweight and safe if downloaded from the official GitHub repo.

    If flyby11 does not work, then you can try WinUpgradeMate app instead. It is one of the best alternative to flyby11 for Windows 11 upgrade from Windows 10.

    WinUpgradeMate is a very powerful utility designed to help users perform an in-place upgrade from Windows 10 to Windows 11 on machines that don't meet Windows 11 official hardware requirements.

    It offers two different ways to upgrade Windows 10 to Windows 11.  And most importantly, it can keep your personal files, apps and settings.

    How it works:

    Download and install the WinUpgradeMate application.

    Import an official Windows 11 ISO, and choose a setup mode. The Quick method applies a technique that launches a server/product install path to avoid compatibility checks. And the Standard method modifies registry entries to relax checks.

    There might be a problem with the Flyby11 download if users are experiencing difficulties such as failed downloads, corrupted files, or installation issues. Sometimes, issues can stem from the server hosting the download, compatibility problems, or restrictions like firewalls or antivirus software.

    Common issues include:

    • Verify the official source for Flyby11 and check if there's a version compatible with Windows 11.
    • Click "Flyby11 download" again. Redownload the installer to ensure it's not corrupt.
    • Run the installer as an administrator.
    • Temporarily disable antivirus/security software during installation.
    • Try running the installer in compatibility mode for an earlier Windows version.
    • Check for any specific instructions or updates from the Flyby11 developer.

    It sounds like you're using FlyBy11, a tool designed to bypass hardware compatibility checks and facilitate Windows 11 installation on unsupported devices. While the download and initial steps seem successful, the setup not continuing after the compatibility check indicates potential issues. Here are some common reasons and troubleshooting steps:

    • Incompatibility Beyond Checks:
      Even if FlyBy11 bypasses certain checks, some hardware components or system configurations might still prevent the upgrade from proceeding. Ensure your PC meets the minimum requirements and that no hardware issues are detected.
    • Secure Boot and TPM Settings:
      Windows 11 requires Secure Boot and TPM 2.0. Verify that these are enabled in your BIOS/UEFI settings. Sometimes, even with FlyBy11, these features need to be enabled, or the tool might modify these settings automatically.

     

    What is the flyby11 alternative If FlyBy11 isn't working?  Considering creating a bootable Windows 11 installation media using the official Media Creation Tool and then performing a manual upgrade. Be aware that unsupported hardware may still face issues, and Microsoft might not support upgrades on such systems.
