Hi Guys, We are having Office 2007 Professional Plus [Open License] for our corporate users. But we can't install it in any of our users system. Error: When we insert the Office 2007 CD into the drive, It automtically starts the installation. After some time it stops the installation and closes automatically without showing any error message. Our setup: OS-Windows Vista Business SP1 / Windows XP Professional SP3 and existing Microsoft Office 2003 Professional uninstalled. Thanks in advance. Arun
