Updating

When a new version is out, a small red 1 appears on the RetroInbox button, and its menu shows a Download button.

Download the new ZIP and unzip it.
Copy the new files into your existing RetroInbox folder and replace the old ones.
On chrome://extensions, click the round arrow ↻ on the RetroInbox card. Your settings and your license stay as they were.

Do not remove RetroInbox to update it: removing it also removes your license from this computer. If you do need to remove it, open its menu first and click Release the license, so you can activate your key again afterwards.

If something looks wrong

RetroInbox was switched off after a Chrome update. Chrome sometimes turns off extensions that were not installed from its store. Open chrome://extensions and switch RetroInbox back on.
"Load unpacked" says the manifest is missing. You chose the folder one level too high or too low. Choose the folder that directly contains manifest.json.
"This key is already active on another computer." Your key can be active on one computer at a time. On the other computer, open the RetroInbox menu and click Release the license. If you can no longer use that computer, write to us and we will free your key.
