Maybe this can be done in Office XP installation. Not sure about other
version. Read the following article.
Q: Can I avoid macro viruses altogether by installing Office without Visual
Basic for Applications?
A: In response to customer requests, Microsoft has designed Office XP so
that it can be installed without Visual Basic for Applications (VBA), which
can be appropriated by malicious macro viruses. In the Custom Installation
Wizard, VBA appears in the feature tree on the Set Feature Installation
States page. To deploy Office without VBA, you set the installation state to
Not Available or Not Available, Hidden, Locked.
