• Error - 646, while trying to install KB977304.

  Any attempt KB977304 installation. Install fails error 646, been round on Help FAQ sites and this is the second time that I have followed the links on this forum. Tried deleting download malicious malware it freezes also. Don't know what a manual download, but followed this link too and entered in the update #.  It will start and get to a point and everything freezes. This is also linked to an Itunes installation failure. I did all of their suggestions, until checking my windows settings, which is what brings me here. Thought it might be something to that day. BTW KB977304 was not install for a while now.
  

  Ideas:

  • You have problems with programs
  • Error messages
  • Recent changes to your computer
  • What you have already tried to solve the problem

  But now, to start the installation, I get the error message 'No Win32 Application valid'

  There is a good chance that you see the effects of a hijackware infection!

  NB: If you had no installed anti-virus application or subscription has expired * when the machine was first infected * and/or your subscription has expired since and/or the machine is not kept fully corrected in Windows Update, don't waste your time with any of the following: Format & reinstall Windows.  A repair install won't help!

  1. see if you can download/run the MSRT tool manually: http://www.microsoft.com/security/malwareremove/default.mspx

  NB: Run the FULL scan, not analysis FAST!  You may need to download the MSRT on an uninfected machine and then transfer the MRT. EXE to the infected machine and rename it to SCAN. EXE before running it.

  2A. WinXP-online Windows Live Safety Center scanner 'Protection' (only!) in Mode safe mode with networking, if necessary:http://onecare.live.com/site/en-us/center/howsafe.htm

  2B. Vista or Win7-online this scanner instead: http://onecare.live.com/site/en-us/center/whatsnew.htm

  3. now post the logs required in a forum appropriate for support by an expert in the field. DON'T SKIP THIS STEP!

  I can recommend the assistance of experts available in these forums: http://spywarehammer.com/simplemachinesforum/index.php?board=10.0, http://www.spywarewarrior.com/viewforum.php?f=5, http://www.dslreports.com/forum/cleanup, http://www.bluetack.co.uk/forums/index.phpand http://aumha.net/viewforum.php?f=30

  If these procedures look too complex - and there is no shame in admitting this isn't your cup of tea - take the machine to a local, good reputation and stand-alone computer (that is, not BigBoxStoreUSA or Geek Squad) repair facility.
