Inconsistent port numbers

I recently rebooted the machine where my client runs (I have 2 Raspberry Pi remote servers running licensed VH servers), and when it came back up, the serial ports had different numbers (was COM6 and COM8, now it's COM7 and COM9). How can I prevent this from happening?

Furthermore, my system already has a COM7... so now I have 2! That should DEFINITELY not happen...

Virtualhere doesn't create com ports , it's a operating system setting you need to change

For some reason, Windows thinks those ports are already in use, even though Device Manager isn't showing them. Any thoughts?

I assume you are running the latest virtualhere server and client software version. What operating system is the client running on? And also what chipset is the serial -> USB device e.g FTDI or prolific etc? Its always a good idea to double check you have the latest serial drivers for that chip
