AttachDatabase and Click Once

I am using Click Once to deploy SQL Express as well as the dbf files. The dbf files will be deployed to the data directory.
When my application start up I am using the Server.AttachDatabase method to attach 4 database files to the SQL Express engine. Since the dbf files gets deployed to the below folder that is read only, I am geting the error message below. How do I get around this problem? Please help.

C:\Documents and Settings\user\Local Settings\Apps\Data\5THMDK6K.YTT\KL652YA1.D7J\powe..tion_176981e083d435cc_0001.0001_d3662e0c064603fa

Error 5 usually means that the service account that SQL Server is running under doesn't have read/write permissions in the folder the database is in.

You can fix this by changing the service account (via Start | All Programs | Microsoft SQL Server 2005 | Configuration Tools | SQL Server Configuration Manager | SQL Server (SQLEXPRESS) | Properties) or by granting access to the service account in file explorer.|||This needs to be done programmatically, since it is a ClickOnce installation on a client PC. The folder seems to be read only.
