  • When I try to download updates they won't install, and I get this Error #800B0100. What do I do.

  • I have a similar issue on trying to install KB2656370 after applying SP3.  Went through the MS Fixit routine and didn't solve it.  I wonder if there is a nice fixit to repair any/all update failures.  

  • I am getting a blank gray square covering the download page for either windows installer 3.1.0.0 or 4.5. I am running Windows XP after reformatting my computer. I have successfully updated SP2 and IE 8, but SP3 will not install. The message is "the program requires windows installer 3.1.0.0 (or greater). I can't put my AV back on until I have SP3, and I can't get SP3 without the installer. Why am I getting the large gray block instead of the download button? Help!
