Error message

Could not find a tweak with this name to uninstall

What it means

Thrown by ScriptHelper's Main when, in the 'uninstall' command branch, Tweaks.GetEntry(_appId) returns null - i.e. no tweak is registered under the supplied id. It is an ArgumentException, caught by the generic handler which maps it to an unexpected-error return code (ResultWin32.ERROR_UNEXP_NET_ERR), so the process exits non-zero.

Solutions

1. Run 'ScriptHelper list' first and use one of the ids it prints.
2. Confirm the ScriptHelper build matches the version that registered the tweak id you are passing.
3. Wrap the call and treat a non-zero exit / ArgumentException as 'already removed' if re-running an uninstall script.

Example fix

// before
ScriptHelper.exe uninstall MyAppTweakId
// -> 'Could not find a tweak with this name to uninstall'

// after
ScriptHelper.exe list
# pick a real id from the output, then:
ScriptHelper.exe uninstall <real-id>

// Before invoking ScriptHelper, confirm the id is in its list output.
var ids = RunScriptHelper("list").ParseIds();
if (!ids.Contains(appId, StringComparer.OrdinalIgnoreCase))
    return; // nothing to uninstall

try { Tweaks.GetEntry(_appId)?.OnUninstall(true); }
catch (ArgumentException ex) when (ex.Message.Contains("Could not find a tweak"))
{ /* id not registered; log and treat as already uninstalled */ }

When it happens

Trigger: Running 'ScriptHelper uninstall <id>' where <id> is not a tweak id that Tweaks.GetEntry recognizes; passing the display name instead of the internal id; the tweak list changed and the id was removed or renamed.

Common situations: Calling the helper with a stale id read from an older config; typos in the id string; version mismatch between the host application's stored ids and the ScriptHelper build's compiled tweak set.
