Error Code 800b0100 during install

[sbaune]

I am tring to install Windows XP on my P4 PC, when it's
installing I get the following message:

"An error has been encountered that prevents Setup from
continuing. Setup failed to install the product catalogs.
This is a fatal error. The setup log files should contain
more information. Press OK to view Setup log file."

After pressing OK,

"Error:
The signature for Windows XP setup is invalid. The error
code is 800b0100. No signature was present in the subject.
Setup failed to install the product catalogs..."

Is this an error on the CD or is it something in the XP
software itself that's not working? Any help would be
great.

Thanks

SYMPTOMS: If you try to upgrade to Windows XP on a
computer that runs Microsoft Windows Millennium Edition
(Me), Microsoft Windows 98, or Microsoft Windows 98 Second
Edition, or if you try to upgrade from Windows XP Home
Edition to Windows XP Professional, you may receive one or
more of the following error messages during the setup
process:

Fatal Error:

Setup failed to install the product catalogs. This is a
fatal error. The setup log files should contain more
information.

RESOLUTION: To work around this behavior, rename the %
WinDir%\System32\Catroot2 folder either by using the
Windows XP user interface or at a command prompt.

To rename the %WinDir%\System32\Catroot2 folder at a
command prompt, follow these steps:
While you are in setup and while the error message is
displayed on the screen, press SHIFT+F10 to start a
command prompt. At the command prompt, type
cd\windows\system32\, and then press ENTER.
Type rename catroot2 catold, press ENTER, and then restart
the computer. Try again to finish the upgrade.
If you cannot start a command prompt in setup, boot from a
Microsoft Windows 95, Microsoft Windows 98, or Microsoft
Windows Millennium Edition boot disk and rename the %
WinDir%\System32\Catroot2 folder, or boot from the Windows
XP disc and rename the folder in Recovery Console.

STATUS: Microsoft has confirmed that this is a problem in
the Microsoft products that are listed at the beginning of
this article.
