.NET Framework 4 (re)install/update error !

Yesterday Windows Update offered me security update for .NET Framework 4 KB2572078 .

# The install failed and the cause might be:


1. i recently deleted C\Windows\Installer (not a smart move but it grew way too big )

2. some months ago had some Visual Studio 2010 uninstall problems as well (removed it with the clean up utility but i'm not sure it was done well)


## I already tried:
1. Uninstalling Framework 4 from Windows Add/Remove Programs (no luck)
2. using Windows Install Clean Up (no luck)
3. using .NET Framework cleanup tool (removed it)
4. cleaning with CCleaner for registry/temp files
5. Reinstalling it from Windows Update (no luck) & Manual Install with both Web and Standalone Installer full and client version. (no luck)
______________

### More Details:


-I still have Microsoft .NET Framework NGEN v4.0.30319_X64 and X32 services even if i get error on trying to start them "the system cannot find the file specified"

-On manual install, it rollbacks the progress during installation of .Net Framework 4 Client profile then i get fatal error and a windows setup error.


I attach the log file along with the setup utility log file, MSI log (.rar archive) and screenshots of the windows setup error and Event Viewer logs.

Any suggestions? Thanks in advance.
