Error 'The database XXX doesn't exist!' when installing

I'm trying to install nopCommerce on my remote host (Aruba) after a succesfull installation locally.
During install wizard i receive advertisment about the NETWORK SERVICE permissions. I don't think my web host can permit this policy so i've skipped it.
On the Step 2 i've inserted all parameter and after clicked Next the wizard response
'The database XXX doesn't exist'
I've tried the same credential on a simple aspx with a manual SQLConnetion and all seem to work.
I think it can be some problem with permission or schema name, but the error seems very strange.
Anyone can help me? Does anybody has installed nopCommerce on Aruba?
Thank in advance.

Browsing installation code i can see nopCommerce search for the DB name in master.sysdatabases.
In the Aruba MSSQL doesn't exist this row.
I'll try to bypass this check, but there's another issue: all sql scripts are related to DBO schema but in this situation a must use another schema.
Have i to manually find/replace in the scripts or nopCommerce provide a schema selection?
thank you

Did someone knows how to configure the DB for aruba?
it's necessary to change the .sql scripts?

-->bovac

NETWORK SERVICE must be granted read write execute permissions

I just do the following..
Copy the content of the archive with no source to the site, mod the .sql scripts replacing all the [odb] tables calls with my username like [msqXXX] and it goes like a charm..

@scompo
