Hello,
I haven't seen this issue before myself, but I found some older forum posts that suggested this was an issue with the configuration of the SQL Server users. Typically the Aras Innovator installer handles this configuration of the users automatically, but I've seen people report other login issues when they tried to install Aras Innovator onto a machine that they did not have admin privileges for.
I'd recommend trying to configure these users manually to see if that resolves the issue. Section 8 of the Aras Innovator installation guide covers how the users in SQL Server need to configured. You can find that document as well as some other useful guides here.
