With Dexpot already installed, you might see error messages during the installation process saying that hooxpot(64).dll was still in use and could not be overwritten. In that case:
1. Make sure 'Settings > Start with Windows' is disabled.
2. Quit Dexpot and restart Windows.
3. Run the installer again.
4. Enable 'Settings > Start with Windows' where necessary.
It's easier to enable automatic updates for Dexpot to avoid issues mentioned above.
