problems installing security patch of sql server 2000

Hi, in my company the it security departament is demanding to us to
install some patch that avoid some problems with sql server security.
One of this patch is: SQL2000-KB815495-8.00.0818-ENU
When i installed it on all the servers it was fine, but today i try to
install it on a server that has two instansce of sql server. (inst1 and
inst2)
The inst1 get the patch installation but the inst2 doesn´t. When they
scan the server it seems that the patch is not installed because the
inst2 didn´t get it.
Do somebody know how can i install the patch on a second instance'
thanks a lot for your help.

Don't just participate in USENET...get rewarded for it!When runing the security patch setup, one of the setup windows will prompt
you for what instance to update. You have to run the install for each
instance you wish to update.
