• Error code 8E5E0147, impossible to get Windows Update to work

  When I try to download windows updates I get the following error code: "8e5e0147" and none of the updates will be installed. I now like 15 important updates.

  I already searched this forum and other forums of solutions, but none of those I've tried seems to fix the problem. That's what I tried:

  • Disabled Antivirus and firewall software
  • Tried to install updates and
  • Manually install the updates by microsoft download. This give me an error code, just "failed to install".
  • Run a checkdisk, no errors.
  I would be really happy for more information, which will solve this problem for me. It is very annoying. It is the system that I use if that would be any help:

  Windows 7 Edition Home Premium x 64

• Setup KB967044 error; I get the error code 646 in automatic and manual update update fails so

  I tried to install KB967044 for Microsoft Works 9. Like others, I get the error code 646 for the automatic update. I tried to manually install, but installation requires the CD of Microsoft Works. Now, Works has been installed at the factory, and I do not think that the CD that came with the computer. In any case, I was unable to find such a CD. Disable my firewall has not changed the problem. I use Vista.
  Thank you for your help.

  Contact the manufacturer of your PC to get the drives concerned etc..
