[Zope] Upgrade to 2.7.0: servic-start problem and copy of data.fs

Hi all, Two questions for my upgrade from 2.6.4 to 2.7.0 on Windows NT 4.0 sp 6a 1) I have installed Zope as service, but when I start Zope Service I have this message: The procedure entry point RegisterServiceCtrlHandlerExW could not be located in the dynamic link library ADVAPI32.dll In Google I have seen another person with this problem, but no solution: there are hints? 2) I have simply copied my old data.fs in Zope-instance var: (nearly) everything seems work, but is this correct or it is better exporting and importing my Zope-site folders? Thanks Michele
