Can I delete the Office 2007 Trial?, and must I activate?

[Stan]

Using Win XP Pro.
After using Office 2003 for some years, I recently downloaded the Trial
Version of Office Professional 2007.
I subsequently installed a (non-trial) full version of Office Enterprise
2007, requesting that all previous versions remain.
In Control panel > 'Add or remove Programs' I now have:
Microsoft Office Enterprise 2007 --- 710MB
Microsoft Office Professional 2007 Trial --- 563MB (to expire end Dec 2007)
Microsoft Office Standard edition 2003 --- 376MB
I will be using Enterprise 2007, and my wife prefers using Standard 2003.
Can I remove the Professional 2007 Trial without causing any serious
problems?
If the answer is "yes", will there be any changes at all to operation of any
part of Enterprise 2007?
....
Must I activate all the parts of Enterprise? (In all programs my name
appears under "This product is licensed to"
What are the benefits of activation?

You can attempt an uninstall, it may or may not work.
You will probably have to repair enterprise after any successful uninstall
of the trial
Any Trial should have been uninstalled prior to installing any other office
version
(Dont take to much notice of the size reported, its allmost certainly
incorrect)
