I'm performing a CA BI 6.3.0 (JasperSoft) fresh install, using GUI mode. I've chosen the "Custom instalation" option, because I wanted to use a MSSQL server we have. When I reach the "Repository User Details" step, where I need to provide a username for creating in DB, it says that "Database user already exists" (in fact, I've tested any random name and I keep getting this error).
In documentation (link below), it says "The Repository User Details screen appears. Enter a username and password to create a new user, then click Next.".
Someone already experienced this error?
