This is occurring for me also. I followed the guidance for self hosted windows, with no change.

Hi @sijjay , Thank you for creating this issue. We will investigate it and provide feedback as soon as we have some updates.

Hello there👋,
Thank you for reporting this issue.
We were unable to reproduce the error on our end, and it appears to be related to the runner configuration setup rather than the setup-python action. The error you are experiencing could be due to the following reasons:

• Administrator Privileges: Ensure that your self-hosted runner is running with administrator privileges. This is necessary for setting up the appropriate directories and files when downloading and installing a new version of Python. If your runner is configured as a service, make sure the account that is running the service has the appropriate write permissions so that Python can get installed. Please refer to the documentation for further details related to using setup-python with a self-hosted runner.

• Disk Space: Ensure that the runner has sufficient disk space. Lack of adequate space can hinder the installation of Python and other necessary packages.

• Concurrency Issues: If multiple processes attempt to access or modify the same resources (such as the Python installation directory), it could lead to conflicts and cause the installation to fail.

For further troubleshooting, we recommend re-running the job and trying different Python versions with actions/setup-python@v5. Additionally, you can clear any existing tool cache in your runner using the following snippet and re-run the workflow:

- name: Clear any existing tool cache
  run: |
    mv "${{ runner.tool_cache }}" "${{ runner.tool_cache }}.old"
    mkdir -p "${{ runner.tool_cache }}"
- uses: actions/setup-python@v5
  with:
    python-version: ‘3.x’

We hope this information is helpful. Please let us know if you have any further questions or concerns.

Hello @priya-kinthali,
Below recommendation works for me on Windows Self hosted runner.

• name: Clear any existing tool cache
  run: |
  mv "${{ runner.tool_cache }}" "${{ runner.tool_cache }}.old"
  mkdir -p "${{ runner.tool_cache }}"
• uses: actions/setup-python@v5
  with:
  python-version: ‘3.x’
