Error code 643 when trying to update XML Core Services 4.0

Hello,

I am getting error code 643 when trying to apply the following two updates using Windows Update in Windows 7 Home Premium;

- Security Update for Microsoft XML Core Services 4.0 Service Pack 2 for x64 -based Systems(KB954430)
- Update for Microsoft XML Core Services 4.0 Service Pack 2 for x64 -based Systems(KB973688)

I've tried to update over 10 times without success.  I get Error Details: Code 643 for both updates. 

Every other update has installed fine up to now. 

My system specs are:

Windows 7 Home Premium
HP Pavilion dm3 Notebook
AMD Athlon Neo X2 Dual Core Processor L335 1.60 GHz
4GB RAM
64bit Operating System

I noticed that there is no msxml4.dll file on my /windows/system32/ folder. 

Please help. 

Thank you.
