CD/DVD Missing Drivers for iTunes

Two weeks ago I purchased a new computer with Windows 7 64bit and I installed itunes with no problem at first. The next day I get the following warning before itunes would open;

The registry settings used by the iTunes drivers for importing and buring CDs and DVDs are missing. This can happen as a result of installing other CD burning software. Please reinstall iTunes.

I have reinstalled itunes twice so far and still come up with the same warning. When I run diagnostics with iTunes I get the following;
