How many computers can Microsoft office 2003 be installed on?
Below is an excerpt from Microsoft on Office 2007, which I would
assume is a similar policy to what would've been used on 2003.
"Microsoft Office Home and Student 2007 Retail License Terms allow
for installation on three devices. OEM License Terms limit the
installation to the device on which the software was pre-installed.
Read the Microsoft Software License Terms (MSLT) for the 2007
Microsoft Office system."
