I had to resort to using the web installer as the CS MSI installer didn't work (threw error stating it could not find MDAC 2.7 or above - even though I'm running XP Pro SP2 which has the MDAC components built into it - duh!). Download CS 2 web install & unzip. Edit Installer\default.aspx - modify the line: bool INSTALLER_ENABLED = false;so the installer is enabled eg: bool INSTALLER_ENABLED = true; Using IIS admin, create virtual dir (eg 'cs') pointing to the 'web' dir beneath the installation. ......
