Failed to install 4.5.2

Hello everyone.

I have the following problem on a server: I cannot install version 4.5.2

I get an error like: unrecoverable error during installation

One thing confuses me, when I look at my registry editor I see the following:

This means that I have the .net framework 4.5.2 at least) but the various applications requiring the framework cannot be installed.

I've searched through hundreds of forums without finding a solution. If anyone has any ideas, I'd be very grateful.

Thank you very much.
