I have Windows 7 with a 64 bit system and installed an OEM version of Office Professional 2003 as I prefer the older interface. I tried installing it several times. The installation allows me to put in the license number, select which applications I want and seems to fully install. Then, when I select an Office 2003 program such as Access or Excel, it begins to install the program again but never brings up the program. I tried to uninstall it, but it won't allow me to uninstall as it says I do not have administrator priviledges, so I am stuck and need help.
