备份文件不存在，还原失败！

Error message

备份文件不存在，还原失败！

What it means

AppModifier.Restore() calls BackupExists(), which checks every editor's .h.bak file exists AND its BackupFileVersion equals the current FileVersion. If any fails, it throws a plain Exception because there is no valid backup to restore from.

Solutions

1. If a patch was applied earlier, locate or recreate the matching .h.bak before restoring.
2. Otherwise obtain a clean/original DLL and restore it manually.
3. Disable the target app's auto-update, or re-patch after updates (which re-creates fresh backups).

if (!modifier.BackupExists())
{
    MessageBox.Show("备份文件不存在或版本不匹配，无法还原。请提供原始文件或重新打补丁。");
    return;
}
modifier.Restore();

When it happens

Trigger: Restoring when no backup was ever made (patch never ran), the .h.bak was deleted, or the app updated so BackupFileVersion != current FileVersion (treated as a missing/mismatched backup).

Common situations: Restore clicked before any patch; WeChat/QQ auto-updated so the .bak is from a different version; backup files cleaned up manually.
