.NET Framework setup verification tool, cleanup tool and detection sample code now support .NET Framework 4.6.1

I have posted updated versions of the .NET Framework setup verification tool, the .NET Framework cleanup tool, and the sample code to detect .NET Framework install states that support detecting, verifying, and cleaning up the .NET Framework 4.6.1. You can find more information about how to download and use these tools at the following locations:

As always, if you run into any issues or have any feedback about these tools or samples, please let me know by posting a comment on one of my blog posts or using my blog contact form.

    Isn’t 4.6.1’s HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full\Release value now 394271?

    1. Hi Shoek – On the Windows 10 November 2015 Update, the Release value is set to 394254 when the .NET Framework 4.6.1 is installed. On other versions of Windows, the Release value is set to 394271. I intentionally used the smaller of the Release values in the detection code sample so that it will return true regardless of which version of Windows it is run on.

    Hi Aaron,

    While installing .NET 4.6 on Win 8.1 and Win 2012 R2, it prompted me to install KB2919335 and KB 2919442. We install .NET 4.6 silently. Now these security updates asks to do 2 reboot. once after the kb installation and other after .NET 4.6 installation.
    Is there a way by which I can avoid the reboots or install .NET 4.6 directly like I do in Win 7 without any pre-requisites?

    Also, are these KB’s redistributables which I can ship with my application (based on .NET 4.6)? If not, is there a integrated package of .NET 4.6 available which has the KBs packaged into it so that everything gets installed at one go!

    Thank you,

    1. Hi Kajal Biswas – I’m afraid I don’t know the answers to these questions. I’d suggest posting a question on the .NET Framework setup forum at https://social.msdn.microsoft.com/Forums/vstudio/en-US/home?forum=netfxsetup to see if someone there has any experience with those security updates.

  4. Aaron, will you be releasing same for .NET Framework 4.6.2 now that it is out?

    1. Hi Phantom of the Mobile – I support these tools in my spare time, and I will update them to support the .NET Framework 4.6.2 as time allows in the near future. In the meantime, are there any specific issues that you’re seeing with .NET Framework 4.6.2 that led you to try these tools, or are you just looking for them from a completeness perspective?

      1. Nope Aaron,

        I was interested whether all W 10 needed the update or just some. I am on the latest W 10, 1607, and as I suspected, they already had it, when I just went ahead and tried to install it to them. So all I need to install on is W 8.1, which I have on my Test partition.

        BYW, I sure miss the Email reports of your new posts and new comments. I rely heavily on Email to keep me up to date. Email IS NOT DEAD!!!

        Thanks anyway,

        Best Regards,


        1. Hi Phantom of the Mobile – The Win10 Anniversary Update ships with the .NET Framework 4.6.2 installed as a part of the OS, and it cannot be removed, so there is no need to install it on that version of Windows. You will need to install it on the original Windows 10 release and the Windows 10 November 2015 Update in addition to Windows 8.1 if your application needs it.

          There was a change to the MSDN blog hosting software earlier this year, and I’m guessing that there are some changes related to that which affected email subscription functionality. I’m sorry for any disruptions that has caused.
