Yes, there is a way, but it's not guaranteed it will work. Firstly, create another computer user (preferred with Administrator rights). Secondly, locate the application and right click it. Select RUN AS (while you are logged with the first one) and choose the newly created username. Once the application will open, choose another COM port and run diagnostics or the operation you need. Keep in mind that if the software communicates only through one port, it will show you the same error.
