Version 2026.20

Uninstalling ​

Windows ​

Uninstall Raylux from Settings ▸ Apps or Programs and Features, or run the setup program again and choose Remove.

This removes:

  • The RayluxNexus service.
  • Everything under C:\Program Files\Raylux.
  • The Windows Firewall rules the installer created.

It does not remove:

  • C:\ProgramData\Raylux — your project file, historian, audit log, logs, secrets and certificates.
  • The Microsoft C++ runtime, which other software may depend on.

Your data is kept on purpose

An uninstall that deleted a plant's history would be unforgivable, so the data directory is marked permanent. If you are decommissioning the machine and genuinely want it gone, delete C:\ProgramData\Raylux by hand afterwards — and take a backup first if there is any chance you will want the history.

Studio and Lens are separate entries in the same list and are removed independently.

Checking it went cleanly ​

powershell
sc query RayluxNexus                                  # should report it does not exist
Get-NetFirewallRule -DisplayName 'Raylux*'            # should return nothing
Get-ChildItem 'C:\Program Files\Raylux'               # should not exist
Get-ChildItem 'C:\ProgramData\Raylux'                 # your data, still there

Linux ​

Installed from the package ​

bash
sudo apt remove raylux-nexus

This stops and disables the service and removes everything under /opt/raylux.

Installed from source ​

There is no uninstall target. Stop and disable the service, then remove what the install placed:

bash
sudo systemctl disable --now raylux-nexus

sudo rm -f  /usr/local/bin/raylux-nexus
sudo rm -rf /usr/local/share/raylux
sudo rm -f  /usr/local/lib/systemd/system/raylux-nexus.service
sudo rm -f  /usr/local/lib/sysusers.d/raylux-nexus.conf
sudo systemctl daemon-reload

The data directory /var/lib/raylux and logs in /var/log/raylux are left behind, as on Windows — including on apt purge. That is deliberate: it holds your project, your history, your audit log and your TLS key material. Remove it by hand if you mean to.

The raylux service account is also left in place; remove it with sudo userdel raylux if nothing else uses it.
