Hi Martin MontoyaHernandez

In the folder C:\Program Files\Microsoft SQL Server\160\Setup Bootstrap\Log, you may check the log to see if there are any useful information.

You may also do a clean uninstall and re-install for a try.

Please follow the below steps to remove all components of previous installed SQL Server completely:

1. Remove all SQL Server components from 'Programs and Features'
2. Backup the registry
3. Delete the following keys in regedit:

--HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server

--HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer

4. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and delete all the sub-keys referencing SQL Server
5. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and delete all the keys referencing SQL Server
6. Reboot the machine

In addition, please use an administrator account to reinstall SQL Server on your computer(Right click->run as administrator).Regards，

SRO.cab may be related the machine learning features (but I may be wrong).

In any case, I would recommend that you install as few extra components as possible. Thus, do not include Polybase, Machine Learning, Analysis Services etc. If you actually intend to use these features, you can install these later.
