NB_CLT_7.5.0.4.tar missing a binary file?

I just did a fresh NBU 7.5 install for a Master server on RHEL 6.  I'm trying to patch the server to 7.5.0.4 but the tar file appears to be missing a binary file.

NB_CLT_7.5.0.4.tar from http://www.symantec.com/business/support/index?pag... (3 split files)

I combine the 3 split files and run the tar command to extract the files.  I run NB_update.install script, but it kicks back an error message "ERROR: Missing required files in [current directory]: VrtsNB_7.5.0.4.preuninstall.  Viewing the contents of the tar file confirms that VrtsNB_7.5.0.4preuninstall does not exist in the tar.

Is this just a generic file that I could grab and use from a similar system/server's set of patch files?
