Download locations for .NET Framework 1.0 SP3 and 1.1 SP1

Hey all,

The most recent service packs for the .NET Framework - 1.0 SP3 and 1.1 SP1 - were released at the beginning of September and it looks like they are showing up on Windows Update now.  I wanted to provide the direct links to the service packs in case you want to download it without using WU -

I will post some troubleshooting tips if installing these service packs fails for some reason in a separate article either later tonight or tomorrow, plus I want to write up a brief set of guidelines for detection and deployment of these SP's.

In the meantime, I have also been talking to some folks inside and outside of Microsoft who have had trouble getting one or both of these installed, plus I've scanned a few of the longer newsgroup threads about installation problems.  It seems that the overall failure rate for installing these service packs is much higher than for the original 1.0 or 1.1 packages or for 1.1 SP1/SP2, and I'm trying to help figure out why.  If anyone out there has experienced errors installing one or the other of .NET Framework 1.0 SP3 or 1.1 SP1 please let me know.  It would help a lot if you can include any/all of the following:

  1. What SP did you try to install and on what OS?
  2. What was the error you encountered?
  3. Have you resolved the error yet?  If so, is there any information out on the web that you found helpful?

Thanks in advance!

    Had problem installing sp1 for .net 1.1 on XP sp2 (with Norton Internet Security installed…).

    The install would repeatedly hang (tried it overnight) so followed advice found on forum ( which allowed install to complete. Result was successful.

    I had a problem installing .net 1.1 sp1 on Windows 2000 Professional. I got the following error: Microsoft .NET Framework 1.1 — Error 1706.No valid source could be found for product Microsoft .NET Framework 1.1. The Windows installer cannot continue.

    I had .net framework 1.1 on the box.

    I uninstalled the framework, then reinstalled and applied sp1.

    I can’t remember where I found information. Probally Google Groups.

    I have had a problem downloading programs that require Net Framework 1.1.  When I go to download it says premature end of download.  Then I checked Add/Remove Programs and is shows 1.1 being there.  When I try to remove 1.1 it won’t let me remove it either.

  4. Hi Mercury – You can use the steps listed at to clean off and re-install the .NET Framework 1.1, and hopefully that will resolve the issues you are seeing.

  6. Hi Ashish – Can you please let me know exactly what error messages you are seeing in this scenario?
