I started getting this message from my Realtek Audio control program for a few months now. I figured it was probably missing some files, or got corrupt.

I re-installed all of the Realtek drivers, and still the error message persisted.

A quick google search and I discovered it was caused by some security updates from Microsoft. Specifically it was 925902 (MS07-017) and security update 928843 (MS07-008).

Here is a list of applications that Microsoft knows these patches break:

-Realtek HD Audio Control Panel
-ElsterFormular
-TUGZip
-CD-Tag
-Suunto Ski Manager
-BMC PATROL

I would imagine this is only the tip of the iceberg. There are probably a few hundred they don’t even know about.

Either way the fix is simple. You can

1. Run automatic updates.

Or,

2. Download and install KB Update 935448
