.Net Framework 4 Client Setup Error 80070643 RRS feed

  • Question

  • Hello,

    Before choosing to pose this question, I looked over a post entitled 

    Installation failed with error code: (0x80070643) .Net Framework 4

    The response was from a moderator who gave specific instructions and coordinated emails in order to diagnose the issue. I hope for the same, but welcome any individual feedback on how other users have fixed this issue.

    My computer continually attempts to update .NET Client Agent upon shut down and continually fails. There are five updates that continually error out. The error code associated is x643. 

    In attempting to diagnose the issue, I have tried to repair the .NET Client Agent. Unfortunately, when the Client Agent reinstalls, it also errors out. The error it produces is x80070643. 

    Here are the details from the log report :

    OS Version = 6.1.7600, Platform 2
    OS Description = Windows 7 - x86 
    CommandLine = "C:\Windows\Microsoft.NET\Framework\v4.0.30319\SetupCache\Client\Setup.exe" /repair /x86 /parameterfolder Client

    Hope someone can help.

  • Please follow these steps:

    1. Download a fresh copy of the standalone installer for .NET Framework 4.0 Client Profile:

    2. Before running the installer, apply irarab's fix as follows:

    "I went to "C:\Windows\Microsoft.NET" there is a directory called "assembly".

    I looked in the directory and found some subdirectories with lots of old dot net 4 files. I renamed the directory assembly2 and tried to install Dot Net 4 and it worked!!!!

    (You can't delete the assembly directory unless you take ownership of it but you can rename it.)"

    Also, clear your %temp% directory and disable your AV software.

    The %temp% directory is a reference to the Temp folder associated with the current user. To clear it, do the following:

    Sign on to your system with the Administrator user account you will use to run the installer. Click the Start Orb and type %temp% in the search box. The search results will show the Temp folder you want. Click on the Temp folder to open it in Windows Explorer, then delete the entire contents.

    3. Run the standalone installer from step 1 As Administrator.

    If the install fails, provide complete install logs as follows:

    Collect your full install logs as follows:

    Please collect your install logs with this:

    After you run Collect.exe, you'll find in your %temp% directory. Please upload to a public site, like SkyDrive, and post the link here.
