office assistant problem

[Jerry]

Hi all

I created a windows service application by VB 2005 in which I do some
search work in both word and excel files.My enviroment is W2K SP4，Office2000.

All work well except the windows assistant, if the end user and my project
want use word/excel at same time, office assistant cannot be loaded currectly
by the user office and always show a error pop up in which user was told
cannot load assistant and reinstall office or not.

In the application I created instances of one excel application and 2
word applications, at one time I thought 2word app maybe is the problem, but
if I run the same code not by windows service but by a normal GUI project,
there was no problem. I wonder what 's wrong with office code working under
service.

Here is the error message showed by office when end user want to open
assistant:
'There was a problem starting the Office Assistant. Would you like to try
reinstalling it?'
