Change to the windows default " Windows XP Style ". If you are using some other
theme, the problem is usually with a file called: shellstyle.dll (included with
most visual styles).
Service Pack 1 Parser Message: Value creation failed" at line 472" error when
add/remove programs is opened
Can occur after installing SP1 when you are running a non Microsoft visual style
and the folder containing the customised styleshell.dll has a different name
from the themes name (as shown in the appearances tab).
To get rid of this error you can switch back to a Microsoft Theme or go to
/WINDOWS/Resources/Themes/<Name of theme in use> and rename the shell folder to
the name of the visual style shown in the appearance tab. If you have a theme
with multiple variations you must make this change for each subfolder containing
a differing styleshell.dll file
