Already configured for ctrl.bpsystems.ca — you will not be asked for a server or a key.
Right-click the downloaded file and choose “Run as administrator”. That is the whole job — it asks for nothing else.
If Windows shows a blue “Windows protected your PC” box, choose More info then Run anyway. The little setup script is unsigned, but the RustDesk installer it downloads is signed by RustDesk, and it is checked against a known SHA-256 before anything is installed.
Prefer PowerShell? install-windows.ps1
in an admin terminal:
Set-ExecutionPolicy -Scope Process Bypass -Force; .\install-windows.ps1
sudo bash ~/Downloads/install-linux.sh
Debian/Ubuntu, Fedora/RHEL and openSUSE, on x86-64 or ARM64.
There is no scripted setup for Android. Install RustDesk from the Play Store, then Settings → Network → ID/Relay Server and paste this config string:
host=ctrl.bpsystems.ca,key=av9g3v3uXO2v9mLuhQJg2H9okVSAlYcHUvRYN5MWxHE=
