Hi, I am trying to do an unattended installation of winzip though the registry. I have put this in the registry REG ADD %KEY%\066 /VE /D "WinZip 9.0" /f REG ADD %KEY%\066 /V 1 /D "%Programfiles%\winzip\winzip32.exe /noqp /autoinstall" /f but it doesn't work as it tries to install winzip I get the error message "windows can not find 'C:\program' make sure etc.... So it doesn't understand the space in between program and files. How can I get around this. Cheers Yesterdays
