Cannot install Office XP Service Pack 3

My system is not able to install Office XP Service Pack 3 update it fails with am error saying

"Error 1402 Set up cannot open the registry key. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run\OptionalComponents\IMAIL. Verify that you have sufficient permissions to access the registry or contact Microsoft Product Support Services (PSS) for assistance."

I have tried installing the update manually using using OfficeXpSp3-kb832671-fullfile-enu.exe but i am getting same error message again. Is there anything i can try out to install Office XP Service Pack 3 update without any such issues??

I have checked out for "Error 1402: Setup cannot open Registry Key " and have come across below Knowledgeable article. Just go through it and try out the workaround that has been mentioned there for dealing with the error.
