New drives installation

I get this error message at every system reboot (the italian language means: provider error for drives installation - impossible to load the installation program for CDROM. Contact the hardware manifacturer for support.)
I cannot install my two new drives:
Plextor CDROM PX-54TA and Pioneer DVDRW DVR106D even if they’re recognized by my burning programs.
How can I install their drivers definetly?
Many many thanks…
