McAfee Update Error “SDStbRes.dll: The specified module could not be found.”

KB ID 0000421 


Seen with McAfee 8.8i when attempting to update via the McAfee SDAT file. Seen on Windows 7, Server 2008 R2, Server 2008, and Server 2003.


SDStbRes.dll: The specified module could not be found.

When trying to update from McAfee you see the following error.

mcafee update


I was on the verge of ringing McAfee with this, but in the end I managed to update by simply applying the daily XDAT not the SDAT.

What’s the difference? Simply put the SDAT included the latest scanning engine, but at time of writing the version of 8.8 downloaded included the latest scanning engine (version 5400).

download sdat

Then do a manual update.

Finally, check your DAT version.
