Came across this error today after installing adobe professional on a laptop.  When the user opened up word it came up with this error message.  It’s easy to fix and all you need to do is:

1) Open the Control Panel, double-click Programs &
Features, find and select Office 2007 or Office 2003 (depending on whats installed on your computer)

2) Click on the Change button. Chose Add or Remove
Features. From the list, expand Office Shared Features, click on the little
arrow attached to Visual Basic for Applications and select the Run from My
Computer Option.

3) Click Continue. Setup will then install the VBA code that
you need. Note: You may need to put your installation CD so it can copy the necessary files.

Now when you open up Word this error will not appear and you should be all set.
