I know another Windows Update post. I’m just going through a backlog of stuff that I never published & just want to get it up here.
A while back I wrote about a very similar error when installing the .NET 4.0 Framework (KB982671). https://patrickhoban.wordpress.com/2010/09/29
When installing the .NET 4.5.2 Framework (KB2901907) you receive an error code 13EC.
If you try to install it manually you get an error that says, “An error was encountered. Unspecified error.”
If you watch the free space while installing the update you will see it drop down next to nothing.
I tried to free up some space by doing normal disk clean up (i.e. delete temp files, old profiles, etc.), shrank the WinSXS folder (dism /online /cleanup-image /spsuperseded). It got a little further but still no dice. Luckily it was a VDI so I could just “give” it more hard drive space.
I ran the update again & this time it worked.
As referenced in https://www.microsoft.com/en-us/download/details.aspx?id=42642, this update requires 4.5GB of free space for both x86 & x64.
