PowerPod and Lynxterm

when i go to run both of these programs after install i get the "Error reading comcombobox1->comproperty: registry error (win error code: 2) please help

That error means the PC has no serial port. Install an FTDI based USB to serial converter cable and then they will open without issues.

I’d suggest you to completely uninstall the software from your computer and reinstall and see if that fixes the issue.

Com Port issue?
Is the software trying to read/write information from/to the serial port that doesnt exist? do you have a USB Connection?
