Message WZ55

WinZip^® could not access the correct version of the specified DLL. It is possible that the DLL from a previous version of WinZip is still loaded or that the wrong version of the DLL is in the WinZip folder. To solve this problem, verify the DLL in your WinZip folder has the same date as WINZIP32.EXE.

If they are the same, restart Windows and then run WinZip again. Restarting Windows ensures that old versions of the DLL are not loaded.

If the dates of the DLL and WINZIP32.EXE are not the same, uninstall and then reinstall WinZip using the distribution version of WinZip.
