Office 2003 Update: Enterprise Release of Office 2003 Setup.exe is a replacement of the Office 2003 setup.exe file for administrators who plan to deploy Office 2003 with Local Installation Source enabled.
EntSetup.exe supports two new properties: ENFORCECACHE and CACHEONLY. When ENFORCECACHE is set, it blocks the install from occurring if Local Installation Source fails and also disables the Local Installation Source from being removed by the users. When CACHEONLY is set, it creates only the Local Installation Source and does not perform an install at this time. The installation can occur at a later time. This version is the first release on CNET Download.com.
