Hi, In the instructions for an unattended installation, the first step is to extract the files from webinterface.exe for v4.5.1 "To get started, unzip the WebInterface.exe package to a directory. If WinZip is not installed on a Windows 2003 server, you can simply rename the WebInterface.exe program to WebInterface.zip and then expand it using Windows' built-in zip handler. The unzipped contents will include the file WebInterfaceSetup.exe:" Whenever I perform this step I get an 'unexpected end of archive' error. Anyone else having this problem? Andrew
