Error installing One Identity Manager 8.1.2 schema: The required table does not exist.

Hello experts,

I am trying to install One Identity Manager v8.1.2 in a dedicated instance of SQL. I have full permission (sysadmin) in the instance. I already have a empty database (dbowner role assign to my user) but each time I tried to install One Identity Manager, using the existing database or trying to create a new one, I got the following error:

[1000009] Cannot connect to database because required table do not exist.

I do not think the error is due a permission issue because as I said, I have full right.

Someone has the same problem/issue? Any idea?

Thank you in advance.

Beatriz.
