thonny – Command-line note

Deploy Thonny’s Windows installer silently for all users using Inno Setup command-line options, such as thonny-4.1.2.exe /VERYSILENT /SUPPRESSMSGBOXES /NORESTART /DIR="C:Program FilesThonny", to avoid UI prompts and enable scripting in enterprise environments. Pre-configure shared settings by editing defaults.ini in the installation’s Libsite-packagesthonny directory (e.g., [run]nbackend_name = CustomCPythonn[CustomInterpreter]npath = C:Python39-64python.exe) before deployment, overriding defaults without per-user changes.

thonny – Command-line note

Thonny’s Windows installer is built with Inno Setup, so for unattended rollouts you can run the EXE with standard switches like /VERYSILENT /NORESTART /SP- /LOG="C:Logsthonny_install.log" and point it to a central installation directory (for example on a network share) that is pre-populated with a customized user_dir_template tree, ensuring every new user profile gets consistent Thonny settings and plugins on first launch without additional scripting.
