Anyone perhaps know what is going on ?
Two things you can try;
1. Go to "C:\Windows\Microsoft.NET" there is a directory called "assembly".
In the directory there may be some subdirectories with lots of old dot net 4 files. Rename the directory assembly2 and try to install Dot Net 4.
(You can't delete the assembly directory unless you take ownership of it but you can rename it.)
2. Download the standalone installer; Download Microsoft .NET Framework 4 (Standalone Installer) from Official Microsoft Download Center (Before running the above; Clear out your %temp% directory and disable your AV software)
