For older Python versions in the security maintenance status, https://www.python.org/ officially releases only the source code and no installers. But what if you want an easy way to install these versions on Windows? Here, you can obtain unofficial Windows installers for the following versions of Python.

• 3.5.5 to 3.5.10
• 3.6.9 to 3.6.15
• 3.7.10 to 3.7.13
• 3.8.11 to 3.8.13

These installers were built directly from the source distributions published at https://www.python.org/downloads/source/. For each Python version, this repository includes the following.

• 64-bit executable installer (e.g. python-3.5.5-amd64.exe)
• 32-bit executable installer (e.g. python-3.5.5.exe)
• 64-bit embeddable zip file (e.g. python-3.5.5-embed-amd64.zip)
• 32-bit embeddable zip file (e.g. python-3.5.5-embed-win32.zip)
• 64-bit NuGet package (e.g. python.3.5.5.nupkg)
• 32-bit NuGet package (e.g. pythonx86.3.5.5.nupkg)

When running the Windows installer, ensure that "Download debugging symbols" and "Download debug binaries" are unchecked, as these items are unavailable on python.org.

The files are provided "as is" without warranty or support of any kind. The entire risk as to the quality and performance is with you.
