This is the steps I followed.
1) Load Blizzard Launcher 4.0.0.1817 (WoW Version 4.0.0.12803)
2) Launcher downloads a file named "wow-4.0.0.1817-to-4.0.0.1837-enUS-tools-patch.exe" to the Temp folder inside my wow beta installation.
3) Launcher applies this patch and reloads.
4) The error message appeared at this point.
I erased the following folders within the wow folder in case of any possible corruption after I encountered the error.
\Cache
\Data\Cache
\WTF
\Interface
\Logs
\Temp
To note, the Interface folder contains only those items created the World of Warcraft Client when it launches each time.
Here is an image to the launcher error.

And this is what the log file for the launcher has listed.
