Hi,
I get the error:
Object reference not set to an instance of an object
while I am installing the SQL Server 2017 database engine service.
In previous tabs, only the windows firewall gives warning, but I already have made the rule for port 1433. In SSMS, when I try to connect with the database engine, it causes a login failed error (Error 18456, state:1).
I have already tried reinstalling and also tried to use .net framework repair tool, but that didn't help.
Also, I found that interesting thing that I do not have a problem with connecting to analyses services in SSMS.
Any help would be appreciated!
Thank you
