Yes, you can get the Service Pack 2 update (SP2) if you go to Windows Update and get all of the updates for your computer. This is assuming you have Windows XP.
Installing the software prior to the driver is fine, as long as you install the driver before plugging in the NXT.
ROBOTC requires having SP2 installed otherwise it will not work as expected.
If you have any other problems please let me know.
