After updating to the latest version of HDoujin Downloader, your settings and download queue will remain intact. To be totally safe, you can create a copy of your HDoujin Downloader folder before updating, or create a backup of your settings by going to File > Export backup.
Updating through the updater
If you downloaded the full ZIP archive from the homepage, the updater will be included inside of “bin\updater.exe”.
To update, open HDoujin Downloader and go to Help > Check for updates. If updates are available, click the “Download new version” button and the update will be downloaded.
Updating manually
If you downloaded the standalone executable-only version of HDoujin Downloader, you won’t have the updater included and will need to update manually. This process also works if you’re unable to update through the updater for some reason.
Download the latest version from the homepage or the Releases page, and extract the ZIP archive over top of your current HDoujin Downloader folder. Allow it to overwrite any existing files.
