cannot install Adobe Shockwave Player 11, no admin access - jrfan880

OK, try this one:  I have tried installing this software left, right, up,
down and safe mode and no matter what, I get the same error message: "you do
not have access to make the required system configuration modifications.
Please rerun this installation from an administrator's accout."  Well, I
have.  Over and over.  Tried the built-in admin account - nada.  I am listed
as a system administrator, and it don't work there either.  Even tried the
that needs to be turned on?  Or what?  Tried the ctl-alt-del bit too, didn't
work.  What am I missing?  Using WinXP Pro, SP2.
