    I have a clean install of Windows 11 21H2 (22000.194) and I'm currently not able to install Razer Synapse 3 on it. The system is up to date.

    I do realise that there is no "official" version for Windows 11 available yet, but when is it planned to be released?

    No other software/hardware is having issues on my PC.

    The installation reaches about 40-50% and then just crashes without error pop ups. I have tried launching the installer multiple times as either regular user or admin with the same result.

    I have found the solution to my problem.

    Cause: Plugged in headset - Kraken Ultimate
    1. Unplug the headset
    2. Uninstall Kraken Ultimate driver in Device Manager
    3. Do not plug Kraken Ultimate yet!
    4. Install Synapse software (RazerSynapseInstaller_V1.0.150.988.exe) -> this time it succeeds!
    5. Launch Synapse and login (it may offer an update)
    6. Plug in Kraken Ultimate
    7. All working all dancing

    Have had similar problems due to various USB devices plugged in during updates. Even had a PC hang during startup because of a problem initializing a USB device. Unplugging external devices and in some cases deleting device drivers and letting them reinstall solved most of these problems.
