RUNDLL error after clicking on the System Restore Tab

[PATIENCE]

When I click the "System Restore" tab of the System Dialog, I get the following Error:
RUNDLL

An exception occured while trying to run "shell32dll, Control_RunDLL
"C:\Windows\System32\sysdm.cpl", system"

Go to Start - Run and type %Windir%\INF then press enter.

In Windows Explorer go to Tools - Folder Options - View Tab and uncheck “Hide extensions for known file types”.

Find the sr.inf file, right click on it and select Install.

Or simply type or paste the following command into the Start - Run box and press enter.

Warning: Reinstalling System Restore will delete all existing restore points.

If the Files Needed dialog box appears, click Browse and point to one of these locations:

• The i386 folder on the Windows XP CD.
• The i386 folder on the hard drive, if it exists.
• The C:\Windows\ServicePackFiles\i386 folder if the systems has been updated to Service Pack 2.
• The retail version of Windows XP (SP2) CD contains the latest version of the files needed also.

If after reinstalling System Restore this error message is received, “System restore was unable to start due to a missing Framedyn.dll. Please reinstall the application to fix this problem.”
