As the Administrator Flash won't work, as another user Flash works

Question

I have an HP with XP home edition SP2. I'm set up as the
administrator and my son is set up as an user. I'm running Flash
9.0.115 and generally have no problems. My son goes to the Webkinz
website and logs on and plays the games and has no problems. When
my wife goes to the same web site and logged on as the
administrator all she gets is a white screen. When she logs on
using my sons account she has no problems. I;ve noticed a few other
sites where I get the black screen but if I log in under my son's
account I have no problems. I've tried all the fixes and trouble
shooting tips I can find but nothing works. I had no problems at
all until we up graded to version 9.

Answer 1

The problem is that Flash Player 9 creates registry keys that
grant permissions only to the administrative user who installed it,
and no others. I've tried uninstalling and reinstalling from anothe
administative user account, and then the 2nd account can use it and
the first cannot. I've gone in and looked at permissions on the
registry keys with both installations, and it's clear Adobe's
install sets up registry key permissions for just one user. I've
verified this on one of our home PCs and one work PC, both running
Windows XP SP2. I've reported it to Adobe support and have been
waiting since Jan. 3, 2007 for a response.
