Vista - System Permissions (followup)

Following my previous post regarding System Permissions the scenario
has changed.

This program of ours will run on installation by the administrator.

It will create a folder in documents and settings\allusers\application
data
It will then create a file in that folder called config.txt (let us
say)

I need at this point to be able to set the system permissions for this
file so that all users who log on have security permissions to write
to this file at this point.

When other users log in I want them to have write permissions to this
file.

I have mamaged to create the file as read/write for the administrator,
but not change the permissions yet.

Can THIS be done please and HOW?

Something like this, maybe:
System.Security.AccessControl.FileSecurity fs = new
System.Security.AccessControl.FileSecurity();
fs.AddAccessRule(new
System.Security.AccessControl.FileSystemAccessRule("All Users",
System.Security.AccessControl.FileSystemRights.Write,
System.Security.AccessControl.AccessControlType.Allow));
System.IO.File.SetAccessControl("c:\\documents and settings
\\allusers\\applicationdata\\config.txt", fs);
