If you have chosen the local database file option, please follow the following steps:-

• Download your unique database file from Rolosoft.com. (Note: Database files are updated weekly and for optimal accuracy need to be downloaded and installed frequently).
• Install the file to a folder that is available to the security account that ASP.net runs under (usually NETWORK SERVICE for IIS6). We would recommend creating (if you don't already have it) ./App_Data folder in your application.
• Modify the <settings ...> attributes. Please see Configuration for details.

A default ASP.NET installation runs under a local account with limited permissions. Please ensure that this account (NETWORK SERVICE for IIS6 ) has sufficient permissions access the data file. The minimum permissions required is Read. (Note:) Write/ modify access is NOT required.
