Q: itunes download compatibility withwindows XP

When installing itunes to my dell inspiron 9300 laptop, it stops short and says that "the software you are installing for this hardware

DVD/CD-ROM drives has not passed windows logo testing to verify its compatibility with windows XP" .  This hardware will

not be installed.

I cannot understand the logic or what it is trying to tell me, I am not installing hardware. Comments gratefully accepted
