99.9% of the time, you will find that Notch installs and runs on your Windows PC without any issues. However, there are a couple of third-party applications that can cause issues:


A handful of Anti-Virus programs incorrectly block Notch from running.

Most commonly we see issues with Bit Defender. You can whitelist the NotchApp.exe file in BitDefender to allow it to run. Follow the instructions on the bottom half of this BitDefender manual page to add a process to the Advanced Threat Defense exclusions list. Ensure that you select the NotchApp.exe file when whitelisting the process.

Nahimic (often bundled with MSI Laptops and Motherboards)

Nahimic is a 3D spatial audio program that is often packaged with MSI laptops, desktops, or components. The Nahimic application / service prevents Notch from starting. Nahimic runs in the background as a service and you may not be aware that it is actually running.

To identify if Nahimic is running.

  1. Open Task Manager
  2. Ensure you are opened to the ‘More Details’ view
  3. Under Background Processes find any processes that start with nahimic.

Terminating these processes or uninstalling Nahimic allows Notch to start.

Error: No DirectX11 capable render device available.

If Notch is unable to access your GPU on startup, it will display this error. The cause is usually that Notch is being run on a computer that doesn’t have a DirectX11 capable GPU (in which case the solution is to run Notch on a different computer, or upgrade your GPU), or that something is blocking Notch from accessing it.

Duet Display (https://www.duetdisplay.com/) devices are known to cause such conflicts. The solution is to uninstall the Duet Display driver and unplug the unit(s) from your computer.

Windows ‘N’ Editions

Windows ‘N’ and ‘KN’ editions miss some key media player features required by Notch. As such these Windows versions are not supported.
