The first thing to do would be to use a directory that is accessible by all users. Typically, you should use a subdirectory on All users documents.

In fact, you should never store user data in Program Files!

An alternative would be to use Application data directory.

Those directories can easily be found using Environment.GetFolderPath function.

If you use Application data, you might want to adjust permission during the installation as I don't think you would be able to do that while running as a user without asking elevation. I don't think it is needed for All users documents (unless default security was messed up).

If this is an ASP.NET app, your code is running under a very limited account.

If this is a normal Windows Forms or WPF, or some other desktop app, the code is running AS THE USER THAT LAUNCHED IT.

In any case, your code cannot grant more permissions to something that it already has as the account the code is running under.
