How to Fix Onlinecheck.dll (OnlineFix64.dll) Errors Without Downloading

没有 "Failed to load onlinecheck.dll / onlinefix64.dll" (Error Code 126) occurs because Windows Defender or third-party antivirus software falsely flags and quarantines the file. You do not need to download anything from external sites, as the file is already on your system inside your antivirus quarantine vault.

Follow these steps to recover the file and prevent the error from happening again.

Step 1: Restore the File from Windows Defender Quarantine

If you use standard Windows Security, the file is safely stored in your system's protection history.

按下 Windows Key, 类型 Windows Security,然后按下 Enter.
按下 Virus & threat protection.
按下 Protection history underneath the "Current threats" section.
Locate the recent blocked threat related to your game or the .dll 文件.
点击 Actions 并且选择 Allow on device 或是 Restore.

(Note: If you use a third-party antivirus like Avast, AVG, or McAfee, open that specific program, navigate to its "Quarantine" or "Virus Chest", and choose to restore/exclude the file).

Step 2: Add a Folder Exclusion

To prevent Windows from deleting the file again immediately after you launch the game, you must exclude the game folder from future scans.

打开 Windows Security and go back to Virus & threat protection.
向下滚动到 Virus & threat protection settings 然后点击 Manage settings.
滚动到底部,点击 Add or remove exclusions.
点击 Add an exclusion 并且选择 Folder.
Select the main directory folder where your game is installed.

Step 3: Verify Game Files (If the file was permanently deleted)

If your antivirus permanently destroyed the file before you could restore it, do not download it from sketchy DLL websites. Use your game launcher to recreate it natively.

For Steam : Right-click the game -> Properties -> 没有. Installed Files -> 没有. Verify integrity of game files.
For Epic Games : Click the three dots ... next to the game -> Manage -> 没有. Verify.

If you need help finding the Quarantine folder for a specific third-party antivirus app, or want to know how to add an exclusion to a program other than Windows Defender, let me know which software you use!
