Hello NVIDIA Omniverse Community! ’m experiencing an issue with my Isaac Sim installation on Windows 11, where the essential ‘python.bat’ file is missing. The documentation indicates this file should be present for Python scripting, but despite multiple reinstallations, it’s nowhere to be found. I’ve checked all installation directories, including hidden files and folders, and used Windows search extensively. My Isaac Sim version is 4.2.0. Could anyone advise why this file might be missing or suggest an alternative setup for Python scripting in Isaac Sim? Thank you!
Thank you for bringing this issue to our attention. After installing Isaac Sim following the official documentation, you should be able to locate the python.bat file in the default installation directory. Here’s where you can find it:
C:\Users\[username]\AppData\Local\ov\pkg\isaac-sim-4.2.0
Hi there! I’ve checked that directory and typed in the file under my file explorer and there are no results.
Hi @vickistavro
What steps did you follow to install Isaac Sim?
After installing Nvidia Omniverse Launcher I ensured that I checked the compatibility with Isaac Sim on my PC by downloading the Isaac Sim Compatibility Checker. After everything looked good I then went back to the Library, installing Isaac Sim 4.2.0. I have also uninstalled and reinstalled it after discovering this issue, but there is still no sign of this file even under my Hidden Files.
Hi @vickistavro
Are you able to navigate to the Isaac Sim installation path mentioned by @VickNV (see Setup FAQ — Omniverse IsaacSim latest documentation, point 4)?
Yes I navigated there but there is no sign of this python.bat file. I also typed it under my fie explorer to see if it was accidently moved somewhere else but I don’t have it anywhere on my computer.
Is there any other solution? Something I’m doing wrong perhaps that I’m not aware of? Or am I able to download this python.bat file manually on my Windows 11?
Hi @vickistavro
Can you run (and share the output) the dir command in a terminal opened in the installation folder?
Of course! Here is the output:
C:\Users\vicki\AppData\Local\ov\pkg\isaac-sim-4.2.0>dir

There is python.bat
Probably you see the next from File Explorer:
You can change your File Explorer options to DO NOT hide file extensions
I forgot that I tried to manually make a python.bat file with the help of chat.gpt and it just outputted a terminal when i selected it. I’m going to delete this file that I created and send you an updated version.

Based on this information, was the python.bat file I installed the solution to this issue? All I did was paste this on a Notepad file “@echo off
REM Set the environment for Isaac Sim Python scripting
set PATH=C:\Program Files\Python310;%PATH%
set PYTHONPATH=C:\Users\vicki\AppData\Local\ov\pkg\isaac-sim-4.2.0\python_packages;%PYTHONPATH%
C:\Program Files\Python310\python.exe %*”
I saved it under python.bat file, and then added it to the PATH. When selecting the python.bat file I manually created, it just opened up a command prompt. Should I do that again to solve this issue I’m having with the original file not being installed?
Hi @vickistavro
Uninstall and install Isaac Sim again to have a valid python.bat file
I uninstalled and reinstalled 3 times, following a tutorial, and there is still no file. Each time I did not remove all of the old files installed on my computer from the previous installation but just selected ‘uninstall’ from the Omniverse Launcher, could that be why it didn’t work? Would you recommend I try deleting every folder related to Isaac Sim, or would that not solve my issue?
Hi @vickistavro
Please, share dir command output after install Isaac Sim?
Format it using ```
```
OUTPUT
```
By the way, do you have any anti-virus software that might be deleting the executable .bat files?
Hi there I will check right now! Thank you for all of your help. Also, I just updated my computer and everything has been deleted so I have not installed any anti-virus software.

Thank you so much for your assistance!
Hi there! have you seen my response?
In you last post
python.bat is there, here is mine, its a brand new instlall on win 10 completely new install
Are you having problems running standalone what is your actual issue?
i did have issues with standalone but it was a silly mistake on my part
Cheers
Scott
Thank you so much for the response Scott! My original issue was trying to control my robot on Isaac Sim with python code under the script editor. This was my first time ever working with Isaac Sim so when the code wouldn’t run and kept outputting error responses I took to different forums and researching why this could be. I kept seeing the importance of this python.bat file. I was searching for a python.bat file in my directory so this python batch file was not appearing. Thank you so much for clearing that up, however would you know why my code is not working in the script editor?
