Hi
I am trying to install NAV 2009 on Windows 7.
After the installation I am getting the error report data as:
Fatal Error During installation.
But 1 strange thing is that Role Tailored Client is installed.
Database Server and Classic client are not installed.

What might be the problem??

I hav installed NAV 2009 n number of times on Win Server 2003 without any problem.

Guys!!
This is the error report I am getting:

Login to NAV Client (sql server option), select the "Demo Database" and delete it or you can Login to SQL management studio and delete the database.
