Part 2. How to Register Video Downloader

Video Downloader provides both a free trial version and a registered version for all users to experience all functions.

免費試用版和註冊版有什麼差別？

All users can use Video Downloader for free within 15 days. The free trial only allows users to download 10 UHD full videos in 2K, 4K, and 8K. If you want to remove the limitations, you can purchase a license from our website and then register the software to obtain the full version.

Steps to register Video Downloader

Your license key will be sent to your email inbox once you have purchased a license from our website. Then, you can register Video Downloader by following the steps below:

• Step 1. Launch Video Downloader and click "未註冊".
• 第二步：填寫您的 電郵地址 （用於購買許可證） 註冊碼(i.e. Registration Code). Simply go to your email inbox and copy your license key to the software.
• 步驟3.點擊“登記" to unlock the full version.

請注意： If you want to use the full version but haven't purchased a license, please press "購買" to buy a license first.

註冊失敗可能由以下幾個原因造成：

• 註冊碼或郵箱地址前後不小心添加了空格。
• 購買了錯誤的許可證版本。例如，Windows 用戶購買了 Mac 版本而不是 Windows 版本。
• 輸入的電子郵件地址有誤。
