"Choose assistant" doesn't work in office2003 on Vista 64

The "Choose assistant" option doesn't respond in Office 2003 Professional
SP2
in Vista 64 and when I click on the "Assistant Gallery" tab, I get a
message that "There is not enough memory available to complete this
Operation"

I have 4 GB RAM of which 1.18 GB is in use , and a 12 GB virtual memory
partition, of which 8.308 MB is in use according to the task manager, so the
error message is obviously nonsens. What can the reason be, and what can I
do to fix it?

It is poor netiquette to multipost. Yammering the same question
repeatedly, redundantly, and incessantly like some spoiled rotten
4-year-old brat is more likely to get you ignored rather than answered.
