I have created a small test program in VS 2017 that simply populates a listbox from SQLite db and allows adding new items to the list. It works fine on the development machine but when I create an installer and then install on another machine, the program runs but when I attempt to get data from the database I get this error “unable to find requested .Net Framework Data Provider”.
I have made sure the db is in c:\db on the target machine. Both machines are Windows 10.
Thanks in advance.
The app.config contentrs are as below.
