I had a server running Zen 6.5 that crashed completely. The server has
been replaced with a nw6.5sp5 server with both the post sp5 nss and
server.exe patches. I removed the old server correctly from the tree.
When I try to reinstall the Zen for Desktops the installation does not
complete. The install log says:

Pre-install steps completed successfully
InvDB components NOT installed
Error: There was an error installing Zenworks Desktop Management
Error: Error copying files to server. Be sure that no ZENworks Desktop
Management files are open or locked.

Did I miss removing some ZEN items from the tree before I did the ZEN
