  I have THREE questions which PEUVENT all be linked togther... What do you think?

  [I am slot as Windows 7 Ultimate (free upgrade to Dell PC w/purchase) on a Dell 64 bit PC XPS435]
  I've upgraded from Vista about 3 weeks ago.

  #1 - Two weeks ago I had a problem with the installation of Nero/LiquidTV-TiVo to my PC... (this is also when the problem started).
  To get the "Nero" thing figured out, I took the advice of someone on the Forum/Blog of Nero. The person has provided a lenghty explanation how to uninstall LiquidTV completely by removing the registry files... I don't really know what I'm doing in the registry, but everything that I helped my problem of Nero, but I couldn't tell you WHAT I deleted OR if I have deleted any bad subfolders or whatnot!... the next time I started my PC is when the NEW NUMBER is right.

  #2 - On my next BOOT, Windows Update has found an IMPORTANT update:

  A security update for Microsoft XML Core Services 4.0 Service Pack 2 for x 64 systems (KB954430)

  .. .and it fails every time, it tries to install saying this:

  Windows Update - failed

  Code 643 Windows Update encountered an unknown error.

  "Get help with this error" provides little or no help... but it says this:
   "WindowsUpdate_00000643" "WindowsUpdate_dt000"
  
  All the research I did, the problem seems to be with Microsoft .NET Framework... .and all the solutions I found talking about it, "UNINSTALL all THE .NET FRAMEWORK & REINSTALL" ... I tried and there is no .NET Frameworks listed in Add/Remove, and when I press on ' VIEW INSTALLED UPDATES'... " on my PC it says, "no updates are installed on this computer"... what the _____?

  #3 - Today, I thought I would just pop the WINDOWS 7 installation disc and do a repair/upgrade... It will not be upgraded.
  He cycles most of the way through, then he Has STOPPED and says this:

  The following problems prevent upgrade Windows. Cancel the upgrade, perform each task, (it lists only a SINGLE task), and then restart the upgrade to continue.

  • Windows needs to be restarted if necessary to system files can be changed before you continue.

    Does not help restart. He tried 3 times and he ends up doing the same thing.
    Is it possible I deleted something out of the register so far here and which is cause of all this?
    If so, is it possible to fix WITHOUT doing a new install of Windows 7?
    OR... anything can be a problem... Please HELP!

    (And please note: I am a first year student college with specialization in computer science... but I just started last semester, so I don't know what I should... yet. - though, I SHOULD have known better than to mess with the registry!) My bad).

    Thanks a lot for your time in advance, and I look forward to hear from you!  VikeMike4

• Code 8E5E0147 Windows Update encountered an unknown error

  Hello

  
  

  Vista has got an automatic update every day for a few days ago but every time the update starts finally fails with this error: "'Code 8E5E0147 Windows Update encountered an unknown error" "

  
  

  What should I do? Vista Help did not help at all. I got the same error.

  
  

  Thank you.

  suiobo,
  Go to Microsoft's download page and select the download appropriate for your operating system, then save it on your PC.  Then, run the update from your PC and see if it will install manually.  If you still have the error and then perform a clean boot and test again.  Let us know the results.
