During the installation of a version 8.0.1 patch file (184.108.40.2062.msp) a message box was displayed with the following message:
Error: 1334: The file 'ccbldll.dll' cannot be installed because the file cannot be found in cabinet file 'PCW_CAT_FAMILY00'. This could indicate a network error, an error reading from the CD-ROM, or a problem with this package.
The patch file that was being installed was cummulative and already contained in a prior patch that had already been applied to the target machine.
Using Windows "Add or Remove Programs" (check "Show updates") dialog box ("Installed Updates" of "Program and Features" on Windows Vista) to uninstall the previously applied patch (version 220.127.116.111) allowed the new patch file (version 18.104.22.1682) to be installed on the target machine.
