I figured out the problem. The example code I was using was:
DbProviderFactory factory = DbProviderFactories.GetFactory( "System.Data.SQLite");
On a clean PC, the machine.config did not have the proper entry for DBProviderFactories
and thus I was getting a Data Provider not found error forcing me to think I needed to install it in the GAC.
So, I changed the code to simply:
SQLiteConnection DBConnection = new SQLiteConnection(connectionString);
Now, it works w/o any thing special during the install...just copy the files.
