Operating system error 5(access is denied) when creating Database at Client Machine in C:\ Drive

Question

I am installing SQL Server Express 2005 as a prerequisite of my c# windows form application, and under the Custom Action of my installer class, I'm trying to execute the script below, to create my database on the user machine.

However when I choose to create the database on the C:\ drive(the windows root folder), I am getting this error/exception:

Operating system error 5(access is denied)

I do not get any error if I try to do so in any other drive.

Please Help me. How can I get the relevant privileges for this SQL query?

Answer 1

Finally reached to the solution Because i was trying to access from a database as from Network Service account . when i changed that to local system it worked ! Here is the code

Microsoft.SqlServer.Management.Smo.Wmi.ManagedComputer mc = new Microsoft.SqlServer.Management.Smo.Wmi.ManagedComputer();
                Microsoft.SqlServer.Management.Smo.Wmi.Service svc = mc.Services["MSSQL$SQLEXPRESS"];
                svc.SetServiceAccount("LocalSystem",null);
                svc.Alter();
                SqlConnection.ClearAllPools();

It changes the service account to localSystem

I came the similar problem. After hell lot of analysis, I figured a simple fix for my issue. Close your Visual Studio. Open it again as Administrator and this should work.

Hope it helps.
