Hello,
I believe the OS comes pre-installed with the machine. Again, it depends from vendor to vendor.
When you start the machine, was there any Norton Antivirus installed OR Symantec Endpoint Protection installed?
In case you have a Norton Antivirus, please make sure you uninstall it along with Liveupdate before installing the Symantec Endpoint Protection 12.1.
In your case currently, it seems you are running an Italian version of OS, correct?
Upon checking your logs, we see the below errors:
ShowServiceProgress: incrementing tick
ScriptGen: ShowServiceProgress() script execution failed.
ScriptGen: ShowServiceProgress() reset script failure event.
ScriptGen: ShowServiceProgress() is returning an error (so close to the end!)
CustomAction ShowServiceProgress returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)

Suggestions -
Please ensure that the UAC, Windows Firewall and Windows Defender services are stoped and disabled on the Windows 7 machine.
Try Creating a custom setting under the “Client Install Settings” options to not use “Add the program to the Start Menu”, leave this unchecked.
Secondly, you are trying to install the SEP 12.1.671.4971.105 which is a RTM version of SEP 12.1.
Could you try installing the SEP 12.1 RU3 (SEP 12.1.3001) on the Windows 7 machine and check if that helps!!
Hope that helps!!
