I've tried reinstalling 4.90Sp2 client with all options, and only
occasionally will the ZENAPPWS.DLL file be installed- one particularly
problematic system has SpySweeper Enterprise, on which I've made two UDP
exceptions (based on their suggestion) as 1761 and 1762 for Remote
Management, thinking this may help- alas, no. All systems here are
WinXPPro, some SP1, Some Sp2- anyhing jump to mind specifically as to what
causes ZENAPPWS.DLL from not being installed?

many thanks
