    My program is not building. What do I do?
    Community Answer
    Refresh it, if that doesn't work, then turn off and then turn on your device. Finally, if that does not work, you should delete and reinstall it.

    I downloaded Code::Blocks, but entered the wrong settings. Now I know the correct ones, but even after uninstalling and downloading it again it does not ask me for the settings, and stays like it was before. What can I do?

    When uninstalling Code::Blocks, there is a prompt which asks you if you want to retain your settings post-uninstallation. Decline this, allowing it to remove the previous settings, then install Code::Blocks again.
