Configure second database for Primavera P6 Version 7 in SQL Server 2008

Dear All,

I am trying to configure a second database for the Primavera P6 version 7 installed with an Oracle Database in my laptop running windows 8.

I have Installed SQL Server 2008 R2 with SP2.

Now I go to the P6-7 Client Installation CD and run the dbsetup from the folder     .

I select/insert the following data

DBA user: sa

DBA Password: sa

Database hostname: mycomputer\SQLEXPRESS

Database Port:1433

Now, after I press next it says connection refused and the following screen comes up.

I have already tried the following as advised by a friend, but without any luck

1. Checked if the sql server services is active
2. Checked the TCP port number and used the same port number when you create a new database.
3. Created an exception in the firewall for this port 1433
4. Tried with computername\SQLEXPRESS in host name.

Now, please let me know where I am doing wrong, and what I need to do to setup the second Database.

Thanks you and regards

Pranab
