If you're installing Web Image Studio on Windows XP and you receive the error message "Msi launch conditions failed. Installation aborted", this means your computer has not yet been upgraded to Windows XP Service Pack 3 with Internet Explorer 7.0 or higher.  

To correct this, run Windows Update and upgrade to Service Pack 3, then re-install Web Image Studio. A complete list of server requirements to use Web Image Studio can be found here.
