When you install Office 2003 from the Office 2003 CD or an image of the CD, Setup installs a system service that is named the Office Source Engine (the Ose.exe file) to copy the required installation files to the local computer. After it reads the Setup settings file, the Setup.exe file determines the drive on the local computer that has the most space, verifies that the user has administrative privileges, and then installs the Office Source Engine.
