While I still believe that Internet Explorer 8 is the right choice of browser for business use at the current time, Google has taken one step forward in making its popular Chrome browser enterprise friendly by making available an MSI installer package. Most importantly, unlike the consumer version, the MSI installs Chrome to the protected Program Files directory, making one installation of Chrome available to all users of the same system and easier to update when deployed across enterprise systems. Needless to say, an MSI file is also helpful when using Group Policy Software Installation or other enterprise-class deployment system. Download the Chrome MSI for enterprise deployment here.
You should note that at the time of writing, the MSI version of Chrome is a beta of version 6.
