ADMIN SET POLICIES TO PREVENT INSTAL?

HEY GUYS
WELL, I AM TIRED OF WRITING THIS SAME QUESTION AGAIN AND AGAIN ON DIFFERENT FORUMS

WELL, ONE MORE SHOT
SEE, I ALWAYS LOGIN AS ADMINISTRATOR
DUE TO SOME PARTICULAR REASON, I UPGRADED MY WINDOWS INSTALLER AND SINCE THEN WHENVER I START REINSTLLING OFFICE XP, IT SAYS “ADMINSTRATOR HAS SET POLICIES TO PREVENT THIS INSTALLATION”

I TRIED IT LOGGING ON AS ANOTHER ADMINISTRATOR (BACKUP ACCOUNT)

BUT STILL CANT GET THRU
PLEASE HELP !!!!!!!!!!!!
