    can't install Update KB4014981

    Win 7 Ultimate
    Getting error all week: "Error 66A" with Win Update
    "April, 2017 Security and Quality Rollup for .NET Framework 3.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2 on Windows 7 and Windows Server 2008 R2 for x64 (KB4014981)"

    Other updates have installed. Did some research.

    One possible solution:

    Another solution?

    I'm checking with Vdr before I uninstall anything from my system. This is scarier than uninstalling a program.

    Dot Net framework security updates are always a pain.

    If you do need to use the cleanup tool, only remove the version 4.x Dot Net Frameworks that you have installed, then try re-installing them from the Microsoft downloads, then try the update again.

    This sounds familiar. Can I live without this update?

    Probably, but I would not recommend it, since it patches a significant security flaw.

    I tried this MS fix, but it didn't work.

    I can't handle this one. I don't do DOS.

    The instructions for the Dot Net Framework Cleanup tool are reasonably good, at least for Microsoft instructions. The tool may be the only way to get your update installed. When I use tools like this, I usually read the instructions through several times, make sure I have downloaded the required files, and have everything ready before trying them process for real. I also make sure to make a current image backup before starting just in case some unforeseen issue occurs that causes an unrecoverable problem.
