Outlook 2000 rules

[radian-epi]

Received message: "Error 1926. Could not set file security
for file 'C:\Config.Msi\'. Error: 5. Verify thet you have
sufficient priviledges to modify the security permissions
for this file."

I was adding to the rules and running one when it told
me "There was an error running rules. Not all rules
applied". I went to Help and tried the repair and
received the 1st error message. I am logged on my
computer as administrator so all priveledes are enabled.

Any help would be greatly appreciated.
