Topic Description


Detailed Description

I’m encountering two issues while running the post-installation scripts of Isaac Sim 4.2.0 on Windows 11.

  • When executing omni.isaac.sim.post.install.bat, the script finishes with a message saying “Isaac Sim Post-Installation Script completed!”, but also shows an error:
    “다른 프로세스가 파일을 사용 중이기 때문에 프로세스가 액세스 할 수 없습니다.”
    (Translation: “The process cannot access the file because it is being used by another process.”)

  • When executing omni.isaac.sim.warmup.bat, I receive the following error in the console related to RPC:
    ConnectionReset from 127.0.0.1
    This seems to happen while warming up the shader cache or establishing RPC communication.

I expected the scripts to run without any file access or communication errors.


Steps to Reproduce

  1. Download and install Isaac Sim 4.2.0 via Omniverse Launcher on Windows 11
  2. Navigate to C:\Users\KIRO\AppData\Local\ov\pkg\isaac-sim-420\
  3. Run omni.isaac.sim.post.install.bat
  4. Observe the message and file access error
  5. Run omni.isaac.sim.warmup.bat
  6. Observe the RPC connection reset error in the terminal

Additional Context

  • No GPU driver or hardware errors noted so far
