When Installing Cura, just uncheck the Install Arduino Drivers on the 'Choose Components' window in Setup.
If you need USB communications, then head over to the Arduino site: Arduino Software
And download the IDE, but when you go to install it you only need to check the Install USB Driver item and uncheck everything else.
Hope this helps.

It's the arduino USB driver and it's needed to communicate with USB cable between a computer and the arduino inside an Ultimaker printer.
pre-installing won't help as the installer does not check to see if it's already installed. There may be a switch to skip over that option but I strongly doubt it. This is not a built in NSIS feature and someone at UM would have had to add that option. Although it's possible. A better solution might be to create your own installer or modify the existing one. I believe everything is open source including the .nsi file that creates the installer.
