Installing .Net Framework 3.5 SP1 on Windows 8 x64 fails and dism at 65.8% with error code 0x800f081f

Question

I am using Windows 8 x64 and would like to install the .NET Framework 3.5. I've downloaded the full package dotnetfx35 from http://www.microsoft.com/en-us/download/details.aspx?id=25150. Installation fails with Error: 0x800f081f the source files could not be found.

Regression:

I've already read How to enable .NET Framework 3.5 on Windows 8 without downloading it?
dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:f:\sources\sxs /LimitAccess fails at 65.8% with error code 0x800f081f
In my win8 iso file's sxs folder, there doesn't exist a .net x64

How can I install .NET Framework 3.5 on Windows 8?

Error: 0x800f081f the source files could not be found

Download the Enterprise Evaluation ISO, mount it and now point to this ISO. This ISO includes the SxS folder.

Enable .Net Framework in Control Panel » Uninstall or Change Programs. Turn Windows Features and check the box Update Windows.
