  2. ignore the direction in the ReadMe.txt file to disable User Account Control (UAC) and reboot

  3. run setup.exe; a setup wizard will lead you step-by-step through the installation

    • on the Choose Components step, uncheck the CNCA0 <-> CNCB0 box before clicking the Next button

To install the current 64-bit version of com0com,

  1. click the Download button here to obtain a Zip archive containing three files: ReadMe1st.txt, ReadMe.txt and setup.exe

  2. ignore the direction in the ReadMe.txt file to run bcdedit.exe, disable User Account Control (UAC), and reboot

  3. run setup.exe; a setup wizard will lead you step-by-step through the installation

    • on the Choose Components step, uncheck the CNCA0 <-> CNCB0 box before clicking the Next button

To create a pair of connected virtual COM ports,
