A 0KB file after download usually means the file was subject to "silent quarantine" or "zero-byte locking" by Windows Defender or third-party antivirus software the moment it was saved to disk. This does not mean the file on the official website is corrupted — rather, the security software's real-time protection mechanism forcibly interrupted the data write process upon detecting characteristics typical of modding tools. 3 steps to resolve the 0KB issue: 1. Disable real-time monitoring interference: Temporarily turn off Windows Defender's "Real-time protection" or exit third-party antivirus software (such as 360 or Tencent PC Manager). 2. Delete the corrupted leftover file: Completely delete the 0KB file that appears. If you don't, your browser may fail to download again due to cache conflicts. 3. Re-download the full installer: Return to the official website gamebuff.cn and click download again. A normal installer package is typically several tens of MB in size. After downloading, right-click the file, select "Properties," and verify that it contains a valid digital signature from 【Game Buff Technology Co., Ltd.】.
