.NET Framework 4.5 'Fatal Error During Installation'

While trying to install Windows .NET Framework 4.5 from the standalone installer onto my laptop, I get the error message 'Fatal Error During Installation'. When installing with windows update, I get the error code (0x80070643).

.NETerrorcode.txt

NB: The CBS.zip file was 38MB, far bigger than the maximum 8. As such, I've uploaded a .zip file of just the CBS log, let me know if this is ok/what else to do.

Thanks in advance for your help guys!

You should be installing .NET 4.5.2 rather than the vanilla version - download it from here...

I've installed this now, but I am still getting an error when launching Autodesk AutoCAD 2015 which is supposedly associated with a lack of the .NET framework. What versions of the .NET framework should I have installed?

This is the link to my thread on the AutoCAD help forums on the matter:

You should probably uninstall AutoCAD, and reinstall it - it's probably because its own .NET installer failed originally, and it's borked the registry entries.
