Hello, It appears Citrix is using a different packaging method for Web Interface 4.5 and 4.5.1 as I am unable to expand the file as well. However, this method does work for 4.0 and 4.2. That being said, it is not necessary to extract the files in order to create a silent install. Further down the CTX article (ctx106114) you'll notice that you can pass arguments to the WebInterface.exe installer by setting the WI_COMMAND_LINE variable. Here is an example: copy /y WebInterface.exe "%temp%\WebInterface.exe" set WI_COMMAND_LINE=-noasc -l en -c "WIDest=1:/Citrix/MetaFrame,PNADest=1:/Citrix/PNAgent,MCMDest=1:/Citrix/MCM, Config=Local,XMLService=MyServer:8080,WIDefaultSite=Yes,FarmName=MyFarm" "%temp%\WebInterface.exe" del /q /f "%temp%\WebInterface.exe" You'll notice that I copy the file first because older versions of the setup did not like to run from network share. Not sure if this is still true for 4.5.x, but this process works regardless.

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
