User does not have enough priviledges on database engine
I have also installed Sql Server 2012 Express -some of the the later versions of 11.0.2100.60 and SQL Management studio 11.02.21.00.60. I have set during the installations of the sql files mixed authentication mode. The I have logged in by using the Windows authentication mode, created new user and then I have tried to use the newly-created user as user for login in Bizagi Studion. Unfortunately I received the above state error when trying doing so.
Could you please aaist in solving the problem ?
Thank you in advance!
