Unity installation error, DISM 87

Unity Engine
1

These days I tried to update Unity (beta) to newer versions (new beta). But, when installation is finishing, the install log print this:
"Deployment Image Servicing and Management Tool
Version: 6.3.9600.17031
Image Version: 6.3.9600.17031
Error: 87"
Then, the installation ends fine but, when I open the engine (on any project), there are every time, two empty errors, that block my development.

I tried to reinstall 3 times, downloaded other 3 versions of the engine (one is stable, and I’ve tried to install in safe mode too), and every time I got these errors.

My windows is 8.1, please, help-me!
