Unity installation error, DISM 87

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!

 

I got the same error is anybody got any info?

My windows is 7 ultimate

Log print
Version 6.3.7100
