cannot install QuickBooks 2005 as well as Windows Update

I haven't been able to install updates since Oct 15 and now can't install a
new program (QuickBooks Basic 2005). I'm trying to resolve the Windows Update
issue - hoping that once this is fixed I can install the software. Here is
what I've done to try to resolve this issue:

I've done the following tips found at http://support.microsoft.com/kb/822798
except for "Method 7". After each method I would try to do the windows update
but it would fail each time.

The critical updates that won't install are:
Microsoft .NET Framework 1.1 Service Pack 1
Microsoft GDI+ Detection Tool (KB873374)
Security Update for Windows XP (KB873339)
Security Update for Windows XP (KB885835)
Critical Update for Windows XP (KB886185)
Security Update for Windows XP (KB885836)

The log that shows the errors are:
