I am using Windows Vista Ultimate.64 Bits. I am running as administrator,
single user.

When I try to install Microsoft Office 2007 Professional, Vista does not
allow the program to run. The dialog box say Office 2007 application is not
compatible.

However, I am able to install and use Microsoft Office 2003.

Is there anyway for me to install Office 2007 to run on this system? Thank
you.
