"System extension cannot be used"?

Often when I am upgrading my software via the "Software Update..." menu option,
such as the recent ITunes update, I get the following error message:

--------------------------------------------------------------------------
^ System extension cannot be used
/!\ The system extension "/System/Library/Extensions/CDSAudioCaptureSupport.kext
--- was installed improperly and cannot be used. Please try reinstalling it, or contact
the product's vendor for an update.

Any idea what this means and how I can fix this?

Thanks in advance

Are you using the latest version of Toast? See this thread:

I am using Toast though (as I haven't used it in a while), I haven't
been using the latest version. I just upgraded now to the September 3rd, 2010
10.0.8 version.
I will reply next time I upgrade ITunes or some other Applecation that may
use this.

Thanks

I have a similar problem, and it's related to roxio's cd spin doctor. and i can't get cd spin doctor to work, despite many e-mails back and forth with roxio support - they keep telling me to try different things, like reinstalling the software (it doesn't install properly because of this cdsaudiocapturesupport.kext, no matter how many times i try) and repairing permissions (also didn't help). even downloading their "update" for toast doesn't help - the download gives a warning that there's a problem with the file. my suspicion is that roxio doesn't really support snow leopard and are just selling software anyway, hoping that customers will get fed up and not be too upset about spending money on non-working software. and all of these threads that suggest the fix is a simple as running the Installl Audio Capture Support on cdspindoctor are useless - this doesn't work either.

To eliminate the error when updating other applications, you have to delete this file from your mac hard drive>system>library>extensions, but forget about ever using the roxio software.
