Hello,
You might want to enable and start the SQL Server browser (this way it's not limited to the specific server name)
If that still doesn't work double check if your windows user has any priveledges to create databases.

Hello
So I activate via the SQL browser and it's still the same message, I leave you this link to tell me if it's OK or not?

Where do I find this?
Thanks Mz

Hello,

In SQL server please try: localhostSQLEXPRESS

Thanks,

It does not work, question, you put that it works better with Windows Server 2012 R2, if I install this version, will it be easier?
Well to you
