Cannot open vsd file using visio viewer 2007

i face the problem that user want to view vsd file without having office visio license, so i installed visio viewer 2003 but it cannot opened,after right-click to allow activeX control and then internet explorer only shown red X only.
so i upgrade to newer version visio viewer 2007 SP2 but the problem still cannot solve. i search and tried to reconfigure microsoft office, internet explorer include security, add-ons and other component for 6 hours, finally i can fix it with simple step, tried to uninstall security update KB973525(Cumulative Security Update for ActiveX Killbits).
OMG…
