Vista Tutorial - Error Code 643

Ok. I am EXTREMELY frustrated about this. I get error code 643. It is because I try to use Windows auto update and it says there are two updates available. When I try to install them, it will not install them. The two updates are: Security Update for Microsoft XML Core Services 4.0 Service Pack 2 for x64 based systems (KB954430) and then, Update for Microsoft XML Core Services 4.0 Service Pack 2
(KB941833). The first one is important, the second recommended. Now,.....I tried following the instructions about downloading the msicuu2 file and right clicking run as administrator. After downloading it and right clicking, I get a window that says:
Window Script Host with a big red x and then:
Script:
C:\Users|COVING~1\AppData\Local\Temp\IXP000.TMP\StartMsi.vbs
Line: 10
Char: 5
Error: The file or directory is corrupted and unreadable
Code: 80070570
Source: null

So, that shoots that down. Now, I followed the advice of another thread and tried to manually uninstall the .net framework programs that I had installed. I went to control panel, remove programs, and right clicked and uninstalled microsoft .net 1.1 software. Then, I followed the recommendations and downloaded new .net software, but when I try to install it, I get the next cute little window (extreme bitterness here people) :
Microsoft .NET Framework 1.1

Info 9006. This patch cannot be installed because it requires Microsoft .NET Framework 1.1 Service Pack 1 (SP1). No Microsoft .NET Framework 1.1 SP can be detected on this computer. Please see Description of the security update for the .NET Framework 1.1 Service Pack 1 for Windows XP and Windows 2000: July 10, 2007 for more details.

I am at my wits end. I hate computers now, forever. All I was trying to do was play some computer games on my nice new fast Gateway PC. I should have never even tried.

I am getting the same error code when I try to install Microsoft .NET Framework 3.5 KB951847 Tried the suggested fix above, but it had no effect. Any Ideas??

I too am getting the same error. I have tried all the things mentioned her to no avail. It's frustrating to me that this seems to me an ongoing problem and there is no fix yet.

I'd like to know the same thing as none of the things here have helped at all.
