Error 13EC when installing The .NET Framework 4.5.2 means you need to free more disk space. 3GB that is.

About a year and a half ago, I wrote:

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.

That is quite difficult when you run loads of VMs on SSDs: they usually don’t have an awful lot of disk space left.

The same issue holds for Microsoft .NET Framework 4.5.2 for Windows 7 x64-based Systems (KB2901983) which got released earlier this week:

It directs to “WindowsUpdate_000013EC” “WindowsUpdate_dt000″ which of course does not give meaningful results in the top hits (:

The uncool thing is that KB2901983 only mentions one requirement: a potential system restart. Nowhere it lists a 3 gigabyte free disk space limit.

And no, I’m not really surprised that the help didn’t improve. Just frustrated.
