How to Uninstall COM Ports Installed by RealPort Drivers in Windows

Items to Note before Starting:
Ensure to document the IP address and COM port numbers already installed on the PC before uninstalling the COM ports installed by RealPort drivers. 
This can include the serial port settings that may have been configured previously.  These may be needed for a reinstall of the driver.

Ensure that the latest RealPort driver is being used, which can be downloaded from the Digi support site. 
The RealPort driver file should be unzipped before running the uninstall process (i.e. -  Do not run the “setup.exe” from within the .zip file).

Always run "setup.exe", no matter if the OS is 32-bit or 64-bit.  If feasible, run “setup.exe” from the computer's local hard drive, not a mapped network drive.
Ensure that the Windows User Account that's running “setup.exe” has Administrative privileges.  Additionally, launch “setup.exe” via right-click / Run as Administrator if the OS offers that option.
