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.

The #Yahoo privacy catch 22: telling to move data but not telling me the source and destination country.

Posted by jpluimers on 2013/12/15

Great move Yahoo (which I only use for Flickr): telling me that Yahoo can improve performance by moving my data to another country without telling which country the data is stored now, and which country Yahoo wants to transfer my data to.

The URL starts with, but does that mean to origin or target country is within Europe?

Of course the Yahoo privacy policies don’t tell either: why would they…

So I cannot confirm, nor deny the provided choice. Nice privacy catch-22!

Generating complex math visualizations in SVG using C# and ILNumerics – Scott Hanselman

Posted by jpluimers on 2013/12/15

Funny how Generating complex math visualizations in SVG using C# and ILNumerics and MathViz (no, not this MathViz!) look so similar.

I hope the MathViz code becomes public one day.
