`syside.modeler.toolsVersion` is a VS Code setting, not a `syside.toml` setting. VS Code stores it in your user `settings.json`, not in the project.

Usually you don’t need to set it. By default, the extension uses the tools version that matches the extension itself. **To use a different Syside version, install that version of the extension** rather than setting `toolsVersion`. If you set `toolsVersion` to a version that doesn’t match the extension, you get an “unexpected version of Syside tools” message.

**To switch to an older Syside version (for example 0.10.3):**

1. **Remove any `toolsVersion` override.** Open Settings (`Cmd`+`,` on macOS, `Ctr`l+`,` on Windows/Linux) and search for `syside.modeler.toolsVersion`. If it has a value, click the setting so that a gear icon appears to the left of its title. Click the gear and choose **Reset Setting**.
2. **Install that version of the extension.** Open the Extensions view (`Cmd`/`Ctrl`+`Shift`+`X`) and click the gear on Syside Modeler. Choose **Install Specific Version…** , then pick the version you want. VS Code then keeps the extension at that version and stops updating it automatically.
3. **Don’t click Update.** The Extensions view will show an **Update** button next to Syside Modeler. Clicking it brings you back to the latest version.
4. **Reload the window:** `Cmd`/`Ctrl`+`Shift`+`P` → **Developer: Reload Window**. The extension installs the tools that match its version.
5. **If the “unexpected version of Syside tools” message still appears,** click **Install Syside Tools** in it and wait for the download to finish. The message stays on screen and highlighting stops until you reload. Then reload the window again.

**To edit the file directly instead,** delete the line `"syside.modeler.toolsVersion": "…",` from your user settings file:

- macOS: `~/Library/Application Support/Code/User/settings.json`
- Windows: `%APPDATA%\Code\User\settings.json`
- Linux: `~/.config/Code/User/settings.json`

**To return to the latest release,** click **Update** on Syside Modeler in the Extensions view. The current stable release is 0.11.0: [Syside 0.11.0](https://forum.sensmetry.com/t/syside-0-11-0/583)
