Ok,
I have followed all of these above, and now there are two .NET Framework in Control Panel right now after uninstalled with the tool and then reinstalled 1.1, 1.1 SP1 and 3.5 SP1. Is that normal?
I then checked the Windows Updates and there are four important updates. All of three are installed fine, except Security Update for Microsoft .NET Framework, Version 1.1 Service Pack 1 (KB929). I already installed 1.1 SP1 from above in the link, and is that why it failed to install because I already have it installed? But, strangely, I already installed 3.5 SP1 from the link and then installed it again from Windows Updates, it installed fine.
I have hidden that update and then checked the updates again. Now there is one update which is Microsoft .NET Framework 4 Client Profile for Windows Vista x64-based Systems (KB982670).
That was installed fine.
I then checked Windows Updates again, and there are four updates which is .NET Framework 4.
Now, only one, Security Update for Microsoft .NET Framework 4 on Windows XP, Windows Server 2003, Windows Vista, Windows 7, Windows Server 2008, Windows Server 2008 R2 for x64-based Systems (KB2518870) installed fine, while the other three failed to install which are,
Security Update for Microsoft .NET Framework 4 on Windows XP, Windows Server 2003, Windows Vista, Windows 7, Windows Server 2008, Windows Server 2008 R2 for x64-based Systems (KB2539636)
Update for Microsoft .NET Framework 4 on Windows XP, Windows Server 2003, Windows Vista, Windows 7, Windows Server 2008, Windows Server 2008 R2 for x64-based Systems (KB2468871)
Update for Microsoft .NET Framework 4 on Windows XP, Windows Server 2003, Windows Vista, Windows 7, Windows Server 2008, Windows Server 2008 R2 for x64-based Systems (KB2533523)
So, I am hiding these for now.
I then checked Windows Updates again and there is one update, Security Update for Microsoft .NET Framework 4 on Windows XP, Windows Server 2003, Windows Vista, Windows 7, Windows Server 2008, Windows Server 2008 R2 for x64-based Systems (KB2478663)
That installed fine.
I noticed there is Security before .NET Framework 4, is that the same as Net Framework 4 or is there I need to install it? As I mentioned above, regarding the three updates failed to install, there are two .NET Framework 4, but they failed to install.
As for other updates, I am really frustrated with these since this morning and am taking a break until tomorrow to try it in SAFE MODE.
Thanks again.
