“Error 1317” during installation

On certain Windows systems, you might get the following error when attempting to install Notch:

Error 1317 An error occurred while attempting to create the directory Drive Name:\Folder Name

This is a Windows error that indicates that you are attempting to install Notch in a directory for which you do not have the correct permissions. This can be because your logged in user is not an Administrator, or that the directory you’re trying to write to is locked in some other way.

Anti-Virus

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.
