Solution 1

"Program Files" in Windows is protected, so normal users cannot write there, your applications will probably work with an administrator user.

Change the data folder path for your database to somewhere where all users have permission to write.

Consult your installer documentation, for your code make the database path a configuration point (instead of hard coding).
