Is there a detailed log for BEST installation?

I have installed BEST this way a hundred of times:

I go to the gravityzone, I download the package "windows download", I run it with administrator privileges, and I usually get a working BEST on that system.

On two pc I am getting different errors:

In one of them (windows 10) I get a generic ERROR message and the installation terminate.

On another one, Windows server 2012, the installer prompt to Reboot the system and tells that it will continue installing afterward, but nothing happens (20 reboots and install attempts already tried).

I also already followed all the steps presented here because I could not find an english guide: https://www.bitdefender.it/consumer/support/answer/22075/

Is there a detailed log for BEST installation?

Kindest regards
