    Thanks for the help but after I had downloaded the update and tried to install it, it failed and said "another installation is already in progress, complete that installation before proceeding"
    Windows update has found this update for me, I am running Windows 10 Pro 64bit.

    Try to restart your computer.

    I have restarted my pc, but it made no difference, the update is still there and still fails to install, giving the same error code.
    I'm concerned that until this one installs I won't get any more updates, is that how it works?

    I have some solutions for
    "another installation is already in progress"
    1. "Select Services, right click on Windows Installer in the list and select Properties. If you’re having the problem, the Windows Installer service is started, and the Stop button is disabled. Simply rebooting doesn’t stop the service. Here’s how you stop it. In the Properties dialog, change Startup type to “Disabled”, click OK, and reboot your computer. This stops the service. After your computer reboots, again open Computer Management (right-click on Computer and select Manage), open Windows Installer Properties, and change the Startup type back to Manual. Now you’re good to go and can start a new installation."

    2.(very easy) Open Task Manager (Ctrl+Alt+Delete or right click on taskbar and click Start Task Manager). Go to process named msiexec.exe and click End Task. Now, start the installation and check.

    3.Look in the STARTUP Tab of Taskmanager for any kind of installer that is set to load at Startup...
    If you find one, disable it.

    Do the same thing in System Configuration (MSCONFIG) Services Tab....
    Check the box to hide all Microsoft services and check out what is left...( It's probably a 3rd Party, but maybe not)...

    Uncheck the box for anything suspicious... You may be surprised by some of the unnecessary stuff you find...

    OK, an update. I found the process "msiexec" it was called installer. I clicked end task and ran the update again. It worked!
    A big thank you to everyone who posted to try and help and especially Hexagon12 for their solution that solved my problem

    OMG.. windows update it's a completely labyrinth!! Every day a new problems appends!

    I have the same exact problems........... i see this on windows update and i obtain the same error code..... i have downloaded the vcredist_x64.exe but when i try to execute i obtain a totally different error.. somethigs say:
    "Error 1935. An error occured during the installation of assembly Microsoft.VC90.ATL etc etc" and near to end says:
    "Please refer to help and support for more information. HRESULT 0x80070002."

    I don't have idea what i need to do.............. i have also tryed to restart and retry to install no success and same error....

    *EDIT*
    I have windows 10 x64 home... i don't have gpedit.msc.......... damn.

    On the chronology on windows update every time i click on restart i can see this:


    Apparently every time the install KB2538242 it's installed successfully but the 243 failed every time. I have also download the offline for 242 and tryed to install manually and obtain a similar error when i lauch the 243 setup.

    How i need to do ?
