.NET Framework cleanup tool now supports .NET Framework 4.5 and Windows 8

  • 發行項

I have posted an updated version of the .NET Framework cleanup tool that supports cleaning up the .NET Framework 4.5. It has also been updated to correctly recognize when it is running on Windows 8. There is more information about how to download and use the .NET Framework cleanup tool in the user’s guide at https://blogs.msdn.com/b/astebner/archive/2008/08/28/8904493.aspx.

As always, if you run into any issues or have any feedback about the .NET Framework cleanup tool, please let me know by posting a comment on one of my blog posts or using the contact form.

    I need to install the RTM version of .Net Framework on Windows 8 Release Preview, but the setup says that "Microsoft .NET Framework 4.5 is already a part of this operating system.  You do not need to install the .NET Framework 4.5 redistributable.". Can I work around this error?

    Hi Fduch - Windows 8 includes the .NET Framework 4.5 as a part of the OS, and it cannot be removed or installed separately from Windows.  In pre-release versions of Windows 8, there is a pre-release version of the .NET Framework 4.5 as well.  If you need to install the RTM version of the .NET Framework 4.5, you will need to install the RTM version of Windows 8.

    When i setup Visual Studio 2012, it notification so! Microsoft .NET Framework 4.5 is already a part of this operating system.  You do not need to install the .NET Framework 4.5 redistributable

    Hi Steve Gate - That is correct - if you install VS 2012 on Windows 8, it will skip the .NET Framework 4.5 because the .NET Framework 4.5 is included as a part of the OS on Windows 8.  Are you able to successfully install VS 2012, or are you getting setup errors?

    Hi Bkd - The .NET Framework 4.5 is a part of Windows 8, so Visual Studio 2012 setup will skip trying to install it.  That shouldn't cause VS 2012 setup to fail though.  What exact error are you seeing when you try to install VS 2012?  Also, can you please use the tool described at blogs.msdn.com/.../6458047.aspx to collect all of your setup log files, upload the file named %temp%vslogs.cab that this tool will create to a file server (such as http://skydrive.live.com), and then reply back here and provide a link that I can use to download your log files and take a closer look?

    Hi Sam - Windows 8 includes the .NET Framework 4.5 as a part of the OS, and it cannot be removed or installed separately from Windows. Version 4.5.50709 is the RTM version of the .NET Framework 4.5, and if Visual Studio 2012 setup doesn't detect that it is installed, then it most likely means you have a pre-release version of Windows 8 (which includes a pre-release version of the .NET Framework 4.5).  You can only install Visual Studio 2012 RTM on the RTM version of Windows 8.

    Hi Mkean21 - The people I talked to suggested that you talk to your account manager to get an official statement about the extended support lifecycle for Windows Server 2003 and the version of the .NET Framework that ships in it.

    Hi vahid - That assembly should have been installed as a part of Windows 8 because Windows 8 includes the .NET Framework 4.5 as a part of the OS.  You might want to try to repair the .NET Framework by doing the following:

  1.  Try to run the System Update Readiness Tool from support.microsoft.com/.../947821.
  2.  Try to repair the files that are a part of your OS by using the steps listed at blogs.msdn.com/.../how-to-repair-the-net-framework-2-0-and-3-0-on-windows-vista.aspx. If none of the above help, then I'd suggest posting a question on the Visual Studio setup forum at social.msdn.microsoft.com/.../threads to see if someone there has any additional suggestions for you to try.

    Hi Ronnoc - What version of the .NET Framework do you need to restore on your Windows 7 computer?  If it is the .NET Framework 4.5, 4, 1.1 or 1.0, then I'd suggest using the instructions and the download links at blogs.msdn.com/.../8108332.aspx to remove and re-install the .NET Framework. If it is the .NET Framework 2.0, 3.0 or 3.5, those are installed as a part of the OS on Windows 7.  You can use steps like the ones at blogs.msdn.com/.../how-to-repair-the-net-framework-2-0-and-3-0-on-windows-vista.aspx to repair versions of the .NET Framework that are installed as a part of the OS.

    Hi Aaron! Does the cleanup tool support .NET Framework 4.5.1 ? Regards Frank

  • Anonymous
    October 18, 2013
    Hi Frank - The tool does not have a separate entry for the .NET Framework 4.5.1, but since it is a service pack-level update to the .NET Framework 4.5, you can choose the .NET Framework 4.5 entry and it will cleanup either the .NET Framework 4.5 or the .NET Framework 4.5.1 depending on what you have installed.

  • Anonymous
    October 18, 2013
    Hi Frank - I looked at the cleanup tool source code a bit closer and realized I will have to make a small update to allow it to fully remove the .NET Framework 4.5.1.  I'll be publishing an updated version of the cleanup tool later today with this update.

    Hi mukesh - The .NET Framework 4.5 is installed as a part of the OS on Windows 8.  I'm not sure what Kaspersky setup does that would trigger that type of error, so you might need to contact their technical support team to see if they can give you more information about what exactly their setup is detecting that is wrong. In the meantime, you can try the following options to see if they help you repair the .NET Framework 4.5 on Windows 8:

  1.  Try to run the System Update Readiness Tool from support.microsoft.com/.../947821.
  2.  Try to repair the files that are a part of your OS by using the steps listed at blogs.msdn.com/.../how-to-repair-the-net-framework-2-0-and-3-0-on-windows-vista.aspx. If none of the above help, you might need to repair/re-install Windows to fix this type of error.  It might also help to post a question on one of the Windows forums to see if someone there has any additional suggestions for you to try before you resort to re-installing Windows.

    Hi aaqil - There are several possible causes of 1935 errors, so I'll need some more information from you in order to be able to diagnose the cause.  Can you copy and paste the full text of the error message for me to look at?  Also, can you try to find the Office setup log files, then zip them, upload them to a file server such as http://skydrive.live.com, and then reply back here with a link I can use to download the log files and take a closer look? You can find information about the names and locations of Office 2010 setup log files in the knowledge base article at support.microsoft.com/.../826511.

    Hi Janica - Does the installer give any more specific error information in this scenario? You're correct that the .NET Framework 4.5 is installed as a part of the OS on Windows 8 and it can't be re-installed separately like it can on Windows 7.  Here are some steps that I typically recommend to try to repair versions of the .NET Framework that are installed as a part of the OS:

  1.  Install the latest Windows service pack if you haven't yet. Windows 8 doesn't have any service packs, but you might have luck installing Windows 8.1.
  2.  Try to run the System Update Readiness Tool from support.microsoft.com/.../947821.
  3.  Try to repair the files that are a part of your OS by using the steps listed at blogs.msdn.com/.../how-to-repair-the-net-framework-2-0-and-3-0-on-windows-vista.aspx. I'd also suggest contacting Kaspersky to see if they have any known issues or patches related to issues installing on Windows 8.

    Hi Calvin - I'd suggest using the steps and tools described at blogs.msdn.com/.../8108332.aspx to fully remove the .NET Framework from your computer and then try to install the .NET Framework 4.5.1 from www.microsoft.com/.../details.aspx.  If the .NET Framework 4.5.1 installs correctly but you still can't install Kaspersky Internet Security, then I'd suggest contacting their technical support team to see if they have any troubleshooting suggestions or patches for you to try.

    Well, when I contacted their tech support team, they blamed it on Microsoft and asked me to contact them. When I contacted Microsoft, they told me to contact some IT Technician. When I contacted the IT Technician, he said he doesn't know much about it and suggested the Internet. When I searched the Internet, I found this blog. And, the wheel keeps rolling. Anyway, I will contact Microsoft once more and then another IT Technician. Thanks for your help though, appreciate it. :)

    Hi Calvin - Were you able to successfully install the .NET Framework 4.5.1 on this computer?  If so, did the Kaspersky technical support team give you any specific reasons why they thought it was a Microsoft / .NET Framework problem as opposed to a problem in their app?  For example, are there any specific errors in their setup log files or something like that? Also, when you contacted Microsoft, why did they tell you to contact an IT technician?  What do they expect the IT technician to be able to do to resolve this issue?  If you have a case number, please send it to me with the email link on my blog (blogs.msdn.com/.../contact.aspx) and I'll try to follow up with the support team to see if they have any more data and see if there is anything I can help with there.

    Hi Theo - The .NET Framework cleanup tool only knows how to remove files, registry keys and MSI products that are a part of the .NET Framework.  It does not uninstall any other products. It is possible that Kaspersky Internet Security requires the .NET Framework and it doesn't work correctly after you use the tool to remove the .NET Framework.  If that is the case, you'll need to re-install the version of the .NET Framework that it needs in order to allow it to work again.

  • Anonymous
    September 28, 2014
    Hi Jelmer - The .NET Framework 1.1 will show a compatibility warning, but it should still allow you to install on Windows 8.1.  Alternatively, you could use steps 1 and 2 from the blog post at blogs.msdn.com/.../385971.aspx to extract the contents of the .NET Framework 1.1 installer without actually installing it.

    Hi Saikat Das - I'm not sure exactly what you're asking here.  When you say ".NET 2005" - do you mean Visual Studio 2005, or do you mean a version of the .NET Framework? If you're looking for Visual Studio information, the data at en.wikipedia.org/.../Microsoft_Visual_Studio will hopefully help answer your question. If you're looking for .NET Framework information, the data at msdn.microsoft.com/.../bb822049(v=vs.110).aspx will hopefully help answer your question.

    Hi! I'm running Win8.1 with .NET Framework 4.5 Multi-Targeting Pack, .NET Framework 4.5 SDK, ,NET Framework 4.5.1 Multi-Targeting Pack, .NET Framework 4.5.1 Multi-Targeting Pack (ENU), .NET Framework 4.5.1 SDK. I'm trying to install .NET 1.1 but to NO AVAIL, even tried dozens of time with "Creating an administrative install point for the .NET Framework, a service pack and a hotfix" with no AVAIL. Every time I get windows installer error: This installation package could not be opened. Verify that the package exists and that you can access it or contact the application vendor to verify that this is a valid Windows Installer package. Any hints? I truly need to install .NET 1.1 so I can run a program that can only use 1.1, otherwise the software does not save information when the program is closed. Thanks in advance!

    Hi celiojedi - The official guidance from msdn.microsoft.com/.../hh925570(v=vs.110).aspx is that the .NET Framework 1.1 cannot be installed on Windows 8 or later, and you will need to work with the manufacturer of the application to see if they have an updated version that will work with the .NET Framework 3.5 instead.
