Office 2003 SP 2 update, missing SKU1E3.CAB but it's not on CD

Today i got a pop up for updating Office 2003 to SP 2. So I downloaded full network version but when i am trying to install it then installer says that it is not able to find out SKU1E3.CAB file. I though that it might be in Installation CD but its not there. I wanted to know if i can get it from somewhere??

I am getting same error when i am trying to install MS Publisher 2007, installation starts up fine and then it comes up with an error saying "Cannot find E:/SKU1E3.CAB file". By now i have tried using cd and have downloaded number of service packs from MS website but no luck yet. Did you found a fix for it??

You both can go through below article and check out if you are getting any help from it.
You receive an "Installation Error: File not Found" or "Error 0x51F" error message when you try to update Office 2003 programs from the Office Update Web site or the Office Download Center
If you don't get any help from above article then you can try using Windows Installer CleanUp Utility further.
