Error 13EC when installing The .NET Framework 4.5.1 means you need to free more disk space. 3GB that is.

Posted by jpluimers on 2013/12/15

Recently I had Windows Update giving me a 13EC error when installing KB2858725: The .NET Framework 4.5.1 that got release lated last November on various virtual machine systems.

It appears that a lot more people suffer from the Windows Update 13EC issue, and most of them have to to with .NET 4, .NET 4.5 and .NET 4.5.1.

Running many virtual machine systems on an SSD based host machine, so I’m always pressed with disk space (hence cleaning the various temporary files directories often). I wasn’t glad with Windows 8 update KB 2821895

Note there are some Microsoft tips to make the size of the C:\Windows\WinSxS smaller, but those still do not remove the Reserve.tmp file.

My conclusion is that various Microsoft updates now require 3 gigabytes of disk space.

This seems to be the case with the .NET Framework 4.5.1 KB 2858725 update, and probably more future updates. I tried installing the KB 2858725 update with slightly less than 3 gigabytes of space (and after the 3 gigabyte reserve.tmp appeared), and I was still getting error 13EC. But with slightly more than 3 gigabyte the update would install.

Like usual, the Windows Update help on Error 13EC is useless, see the below screenshot.


via: The .NET Framework 4.5.1 and its corresponding language packs are available on Windows Update.

    Thank you so much. Solved the problem with the installation KB2901983 (NET Framework 4.5.2 on Windows 7 x64).

    Thanks. Fixed Windows 7 for .NET 4.5.2, KB2901983 too.

  4. Encountered this error installing .NET Framework 4.5.1 update, with slightly over 3 GB of free space. I extended the disk by an additional 5 GB and the update worked just fine!

    3.5 GB free, no change. I still get that error.

      UPDATE: I just freed more disk space (5.81 GB free), and the update succeeded. I monitored the free space throughout the process, and it never dropped below 3.84 GB free. What the **** is Microsoft doing and/or thinking?

        So almost 6 gigabyte is the boundary for you. I really wish I knew what they are doing. And that they were giving more clear error messages.

    Unable to resolve this error by installing directly from the file available on the microsoft site

      Interesting. Note that my error was on a Windows 8 system, and you are running Windows 8.1. I will try that next time when I need to use a Windows 8 system that doesn’t have the update installed yet.
