APP SDK 2.4 OpenCL version problem

version 1.4.879 required, 1.4.815 installed

I've seen a similar problem reported elsewhere for earlier SDK revisions, such as in this thread:

http://devforums.amd.com/devforum/messageview.cfm?catid=390&threadid=145590

though I didn't see a resolution.  Under 64-bit Windows 7, I've installed Catalyst 11.5 and the APP SDK 2.4, and my graphics device is an ATI Mobility Radeon HD 5470.  When I run any of the OpenCL samples, the error:

This OpenCL build requires version 1.4.879, version 1.4.815 installed.

is displayed and the GPU is not usable.  Any idea of what to try to resolve the problem?  I've uninstalled and reinstalled both the SDK and Catalyst to no avail.  Thanks in advance!

BTW, I hesitate to perform a driver clean due to this post:

The output from clinfo is as follows:

*** CAL version mismatch:
This OpenCL build requires version 1.4.879, version 1.4.815 installed.

Aborting.
