Do I need to retain my old PKZIP/SecureZIP library when installing a new build?
A new build has its own standalone library, which does not refer back to any other build. Once you have thoroughly tested the new PKZIP/SecureZIP build, you may remove your old library from the production environment and just add the new library to the library list. Note: Be sure to have only one PKZIP/SecureZIP library in the library list as multiple versions of PKZIP in the library list may result in unpredictable results.
