• Windows Update: failed. __Code 643 windows Update encountered an unknown error. _ * AND * __I cannot repair Windows 7 with the disc either. My guess is: these issues are related...? __

  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

• problem with update of apps - ann unknown error occurred 11503

  Almost daily when I try to update my IOS apps in iTunes I get error - ' could purchase < app > an unknown error has occurred. There was an error in the iTunes store' with error 11503. This is the case most of the time but not all the time. If I try again later, I am sometimes able to update applications. I check the status of the iTunes store and it shows no problem. I log out and back in iTunes (last verse.) and it does not help. The solution is to make the app on the device (iPhone, with the latest IOS) updates. There's other light this or you will suggest fix?

  I know with iOS9 that apple went to a more direct service provider device app store. The main difference was you could are no longer synchronized apps from a device to iTunes, but you could still make it on the other hand, as well as download on iTunes. With "thinning" each device has received a version customized for a specific application for the model of the device but if you downloaded iTunes no thinning version was as long as it works on any iOS hardware. It is in itself would not explain your experience, but I wonder if it is somehow connected and perhaps it is not a version not cleared up (wild guess)?

• "Sync has encountered an error during synchronization: unknown error." Synchronize automatically retrying this action. »

  Hello

  I want to switch to Chrome, Firefox, but I have a problem with the synchronization feature.
  It always displays the following error message: ' Sync has encountered an error during synchronization: unknown error. " Synchronize automatically retrying this action. »

  I already tried this work around, but it did not work: remove my account from syncing, completely reset my Firefox profile, import my favorites of Chrome (using an HTML file), set up a new sync account (using the same e-mail address then that previously deleted).
  But I still get the error message.

  I saw in other threads that could be a problem with the story, so I also tried to delete, but it doesn't work anymore.

  Here is my last sync-log file: https://pastebin.mozilla.org/8219943

  Thanks for your help.

  I finally found a solution to this problem of synchronization:

  I downloaded the add-on 'Housekeeping' and run the integrity check routine, and it seems to have solved the problem.

• Firefox Sync: Unknown error

  I get an "unknown error" in Firefox Sync on my two computers. Here are the most recent error log:

  http://pastebin.com/17HCcAzu

  With the help of Pastebin, because the log exceeds the limit of 10,000 characters.

  These stand out:

  I think you may be affected by an old key recovery being stored. Is is possible to delete the account temporarily and connect to synchronize once more?

  This error, 11503, is connected to the when I try to buy something and it will not through.  Instead, I get this unknown error.  Have tried to look for solutions, but all I can find are for obsolete versions of iTunes and OS X (most recent, I found from 2013).
