I am having problems installing FTDI drivers from windows update and or Windows device manager, what can I do?

If you've been unsuccessful with installing FTDI drivers please visit https://www.ftdichip.com/Drivers/VCP.htm and download and run the setup executable  http://www.ftdichip.com/Drivers/CDM/CDM21218_Setup.zip

Running this executable can often solve many FTDI driver installation problems. You may also want to remove any existing or old FTDI devices using the FTDI CDM Uninstaller. CDM Uninstaller is a free application that can selectively remove Windows device drivers from the user's system as specified by the device Vendor ID and Product ID. It can be downloaded from the following link https://www.ftdichip.com/Support/Utilities.htm#CDMUninstaller
