Can't Install .NET SP1 on XP Pro SP3 RRS feed

  • Question

  • Ok, I've been beating my head against a wall on this one all day...

    I went to run Windows Update on a computer I support remotely (which I say because I'm really trying to avoid the 120 mile trip one-way to do a clean XP install, which I'm increasingly afraid will necessary since there is some presentation software on this machine that depends on .NET and has to be operational this weekend), and first up on the high priority updates was KB951847, which asked to be installed separately. The install failed with an error 0x643. I skipped over and installed the remaining updates. I then went back and did some more research on the 0x643, none of which was helpful. In the interest of brevity, here's what I did most recently to try and resolve the issue (most of my other attempts have been some variation on this):

    1. Log in under the built-in Administrator account
    2. Remove all previous versions of .NET Framework (1.0 through 4) using the .NET Framework Setup Cleanup Utility, starting with 3.5 and working my way backwards.
    3. Reboot
    4. Install 3.5 SP1 Full (I've also tried every combination and order of versions and patches I can think of to no avail)
    5. ERROR! Installing 3.5 SP1 Full ALWAYS errors out. The log file contains:
      [10/19/11,20:27:51] Microsoft .NET Framework 3.0 SP2 x86: [2] Error: Installation failed for component Microsoft .NET Framework 3.0 SP2 x86. MSI returned error code 1603
      [10/19/11,20:28:01] WapUI: [2] DepCheck indicates Microsoft .NET Framework 3.0 SP2 x86 is not installed.
      This happens regardless of whether it's 3.5 SP1 Full or SP1 for 3.0

    Like I said, I've spent all day beating my head against a wall on this one and it really needs to be done this weekend. Any ideas?


    For reference on what I've been using in my attempts to fix this, here are the articles/discussion I've mostly been using (along with many others):
