.NET 3.5 SP1 and Family Update Information


Hi WSUS Admins:


 


We’ve noticed some confusion about the recently released updates for Microsoft .NET Framework 3.5 SP1.  So, let’s see if we can help clarify the differences in the packages.  These updates apply to x86 and x64 computers.  The detailed update descriptions describe both the platform and OS architecture that apply for each of the updates. You’re also likely wondering about the differences in the update titles. Here are the differences:


 


1.      The update titled “Microsoft .NET framework 3.5 Family Update (KB959209)” updates computers already running .NET Framework 3.5 SP1 with the latest compatibility fixes.  So, if you only want to update existing .NET Framework 3.5 SP1 computers with the latest fixes, then approve these packages.


 


2.      The update titled “Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update (KB951847)” will upgrade computers with .NET Framework 2.0, 3.0, 3.5 to the latest version of the .NET Framework 3.5 SP1, and will also apply KB959209 (#1 above). If you want to upgrade/update all of your computers to the latest version of the .NET Framework and apply the latest compatibility fixes, then approve these packages.


 


If  you know you only need the latest compatibility fixes for 3.5 SP1, then we recommend you only approve the Microsoft .NET framework 3.5 Family Update (KB959209).   Otherwise, we recommend that you approve the second update.


 


 


Thanks,


 


The WSUS team

    Having the same issues as well applying the update.  We just recently got our infastructure in place to start utilizing WSUS, a quarter of our network has "checked in and started dl/install updates", and I am getting a 5% fail rate on .net 3.5 SP1 updates.  Still poking around trying to figure out why I am getting roadblocked on this update.

    You’re referring to the Windows XP edition of KB951847, right?

    Yes, it’s indeed a shame that Microsoft seems to be unable to release an streamlined update including only the files needed for x86 systems. Since January 27th, KB951847 for Windows XP systems consits of the WHOLE REDISTRIBUTABLE PACKAGE of .NET Framework 3.5 SP1 plus the Language Pack files on non-english Windows XP systems, resulting in a up to 280 MB download for these systems in case at least .NET Framwork 2.0 is installed on Windows XP pushed via Auto Update and on Windows Update.

    This fact has been and is still UNACCEPTABLE!

    Surprisingly http://support.microsoft.com/kb/894199/en-us on April 23th once announced an updated version of KB951847 "Updated the packages to make them architecture specific and smaller in size" to be released on April 28th. All of the sudden, this announcement vanished on April 28th and (of course) the revised version of KB951847 has not been released…

    I’ve just come away from a first site visit to a potential customer, looking really stupid, because I was unable to successfully apply .NET Framework 3.5 SP1 on all his machines. One took three attempts, one took 40 minutes and a third wouldn’t install at all…

    Very strange… This Family update must be very poorly designed, for it failed to install on 10% of our computers with 0x80070643.

  13. johnny mooneyhan says:

    I wish they would put on here what system these updates are for.  I just got a vista system and don’t know if any of these updates are for this system

  14. Nicolas Melay says:

    Not related, but I don’t know where to post this…

    Is there any way to make WSUS *automatically* approve "needed" updates, and only those ?

    Even when you tell it to only pick up select classifications and languages, WSUS always end-up downloading gigabytes of useless stuff (Itanic or Sharepoint updates, languages you’ve never heard of, etc).

  16. Craig Kalugin says:

    I too have had mixed luck installing this update using WSUS. Were you or anyone able to resolve the problem?

  17. Mantvydas says:

    I’ve noticed that it failed on the XP computers that never had any version of .NET installed. It simply just has nothing to update… Why WSUS offers it at all?

  18. Mantvydas says:

    Besides, I’ve got it failed on those computers that have Windows XP SP2 and Windows Installer 3.0.

    I found multiple: "EEHndlr FATAL: MSI DLL version is 3.0. Version 3.1 is required" inside WindowsUpdate.log of theirs.

    However, I can’t understand why WSUS doesn’t push the Windows Installer 3.1 first, when it is approved from long ago!

    It’s like a closed loop now: .NET Family Update is not installing because there’s no Windows Installer 3.1, and Windows Installer 3.1 doesn’t install because .NET Family Update fails first.

    Moreover, Service Pack 3 doesn’t show up on those computers, because it wants to be the only one needed.

  19. Tim says:

    I have two instances of KB951847 listed on my WSUS server,  both are for X86.  The only difference I can tell from the two updates is that one has just .NET 2.0 and 3.0 listed as superceded updates, and the other one has a much longer list of superceded updates.

    What’s the deal?

    I also agree with the previous comment about how there should be a way to have a separate classification for x64 and Itanium updates.  They’re nothing but wasted space for most people

  20. Hessel Annema says:

    I also have the same issue.  Please add a check that Windows Installer 3.1 must be installed before KB951847 will in stall

    I get a 0x80070645 error and it tells me to try again. I fixed the version back to origional with the troubleshooter, but it won’t update. I will keep on trrying and probably keeep failing.

  22. Brett says:

    I can’t even import 951847 – I get the following notice:

    "This update cannot be imported into Windows Server Update Services, because it does not have the required applicability information."

    What gives?

  23. Jonathan says:

    Okay, the explanation was clear enough. KB959209 will update pcs with net 3.5sp1 already installed. KB951847 will update pcs only with or without net 3.5. However, please explain why I have kb951847 showing up twice and kb959209 not even showing up. Both kb951847 listed twice are identical. Same files inside, same revision. However about 80% of my pcs say they need 1 of them. The other say they need the other. Any help?

  24. MikeF says:

    My question is why do these updates weigh in at a hefty ~250 megs when the framework itself and even together with SP1 is a much smaller package?  How could the mysterious post-SP1 "updates" be roughly 10x the standalone framework?  

  25. Michele says:

    Hello,

    any news for the "Microsoft .NET Framework 2.0 Service Pack 2" ?

    It has been released on the 16 genuary 2009, but there’s still anything on our wsus…

    Thanks,

    So tell me does that mean if my computers are all updated to a certain point then KB951847 is going to faill on all of them?

    Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update (KB951847) x64

    Download size: 25.7 MB – 82.7 MB

    Windows update always says I need this update when I run it. I can download it but, the stupid thing will not install. I have tried many times. Anyone know why???  Is this common?

  30. Umesh says:

    This update was showing up as a needed update for about 100 systems in my network till last week but now it’s showing as not required for all of them. Even if I try to approve the updates it says this update has expired and can not be approved for installation.

    SP1 for 3.5 makes so many programs work better for me. It can be hard to keep track of patches but this one was a great release.

    I also get this notice "This update cannot be imported into Windows Server Update Services, because it does not have the required applicability information."

  36. Mike says:

    Installing this ( or at least the 948609/958481 components of it) seems to cause IIS7 to stop recognising

    Anyone else seeing this?

    Hi,

    we have got problems rollout out .Net Framework 3.5 on Vista clients. Vista SP1 and SP2 are hit. The Framework is downloading to 80 % and stops. There is enough space on the partition and no errors are visible. Reboot doesnt help. It all starts over and over again.

    I wonder whats is going wrong?

    I want to install .NET 2.0, 3.0 and 3.5 with WSUS. Is this possible? I really can’t get it to work without downloading the full installer from Microsoft and push that out via our software distribution system, but that takes AGES.

    So I’d like to use WSUS to do this in the background, any tips? I tried pushing out "Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 family update for .NET version 2.0 through 3.5 (KB951847) x86" (Service Pack classification) with no luck.

    And to be honest, the information on this issue or how to do it really isn’t the best, and the metainfo on the WSUS server is crap and I’m getting frustrated.

  42. deluxe says:

    I’m in the same boat as you, applied it to machines, and yet they aren’t downloading it.

    b.s. – client has .net v2 and installer 3.1.. same procedure you mentioned above.  the client isn’t detecting it as needed.  I’m ready to call ms and submit a case.
