BHOLD Suite - Core Setup Wizard ended prematurely

I am trying to install BHOLD Core. The wizard ended prematurely because of an error.

Verbose logging is saying this:

he property 'SqlStatements' was found with value 'AddLoginB1User1,AddLoginB1User2,AddLoginB1User3,AddRoleB1User,StartInternalProcess,SetAdministrator1,SetAdministrator2,SetDomain'
The property 'AddLoginB1User1' was found with value 'EXEC sp_grantlogin '

CustomAction CoreDBUpgradeCA returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)

Which is weird because the group name is definately correct. Also when I am trying to access the BHOLD portal, I am getting this:

Access to BHOLD is refused for the following reason(s):
