  4. Type: cd /d "C:\Program Files (x86)\Steam\steamapps\common\AoE2DE" (adjust to your path).
  5. Then type: regsvr32 steam-apirajas.dll

  3. Frequent Updates: The developers, Forgotten Empires and World’s Edge, regularly patch the game. Sometimes, an update fails to overwrite the old DLL correctly.
  4. Third-Party Launchers or Overlays: Programs like Discord overlays, RivaTuner, or MSI Afterburner can sometimes flag this DLL as suspicious.
