It seems, IE6-SP1,

(this link is one long line) has to be installed first: most likely the
original IE5 is using in the system. WMP-9 won't work with IE5.

Q: Why do I get the error "UNREGMP2.EXE file is linked to missing export
ADVAPI32.DLL:SetNamedSecurityInfoW" when trying to install the player?
A: Your advapi32.dll file has been corrupted by rogue software on your box (I
believe it is now version "4.71.0118.0", which is not the version it is supposed to
be). In order to fix this, you will need to go the Add/Remove Control Panel, select
the "Internet Explorer" option in this list, and then run the Repair option that it
will offer. At that point you will then need to reinstall the Media Player, but you
should be good to go from that point.

While your error is slightly different, the cause/cure is likely the same.
