Here are the real causes: Modern antivirus software uses heuristic analysis to detect malware. Because steam-api64r.dll is a non-standard DLL that hooks into Steam (a common target for game cracks/pirates), some overzealous antivirus programs flag it as a false positive and automatically quarantine or delete it. 2. Corrupted Game Files After an Update When Call of Duty: Infinite Warfare downloads a patch, the Steam client verifies existing files. If your internet connection drops or your hard drive has bad sectors, the steam-api64r.dll file can become corrupted or partially downloaded. 3. Manual Deletion or Interference Manually cleaning your Program Files (x86)\Steam\steamapps\common folder, or using third-party “PC cleaner” software, can accidentally delete this file. 4. Incomplete Installation If you moved the game folder from one drive to another, or copied it from a friend (without using Steam’s official backup feature), the DLL might not register correctly. 5. Conflict with Cracked or Modded Content Warning: If you have ever installed a crack, cheat engine, or unofficial mod for Infinite Warfare , those files often replace or remove the legitimate steam-api64r.dll . Even after uninstalling the mod, remnants can cause permanent missing errors unless you do a clean reinstall.
