The Windows agent plugin rds_licenses.ps1 wrote its error messages to standard output, the same channel it uses to send monitoring data.

The messages polluted the agent output and could affect unrelated services.

They are now written to the error stream instead, where they remain visible when the plugin is run manually on the console for troubleshooting.
