Unofficial Python Installers for Windows 7 SP1 and Windows Server 2008 R2

Officially, Python 3.9 and above are not supported on Windows 7 SP1 and Windows Server 2008 R2. Here, you can obtain unofficial Windows installers that bring back support for these older Windows versions.

Note: Windows update KB2533623 must be installed for Python to run. Ensure that your computer is up-to-date via Windows Update. Alternatively, you can manually install update KB3063858, which supersedes KB2533623. Update KB3063858 can be obtained at the following link for 32-bit Windows or 64-bit Windows.

For each Python version, this repository includes the following.

64-bit executable installer (e.g. python-3.9.0-amd64-full.exe)
32-bit executable installer (e.g. python-3.9.0-full.exe)
64-bit embeddable zip file (e.g. python-3.9.0-embed-amd64.zip)
32-bit embeddable zip file (e.g. python-3.9.0-embed-win32.zip)
64-bit NuGet package (e.g. python.3.9.0.nupkg)
32-bit NuGet package (e.g. pythonx86.3.9.0.nupkg)
Windows help file (e.g. python390.chm) (3.9 and 3.10 only)

For the more technical among you, these installers were built from the source distributions published at https://www.python.org/downloads/source/, with the following modifications.

Include the file api-ms-win-core-path-l1-1-0.dll in the distribution. This file was obtained from https://github.com/nalexandru/api-ms-win-core-path-HACK and is necessary for Python to run on older Windows versions.
Create full installers that include debugging symbols and debug binaries without needing to download them.
Allow the installer to proceed on Windows 7 SP1 and Windows Server 2008 R2.
For Python 3.11 or higher, remove the usage of features that are not available on Windows 7.
Fix a few bugs in the build scripts.

See Notes.md for more specific details about how I built these installers and how you may build them yourself.

NuGet Packages

To install a .nupkg package, ensure that you have the NuGet Command-Line Interface installed. Go to the directory containing the .nupkg file. Replace target\installation\directory in the following commands with the desired location to install the package.

Command Prompt

For 64-bit Python, run nuget install python -Source %cd% -OutputDirectory target\installation\directory

For 32-bit Python, run nuget install pythonx86 -Source %cd% -OutputDirectory target\installation\directory

PowerShell

For 64-bit Python, run nuget install python -Source $(Get-Location) -OutputDirectory target\installation\directory

For 32-bit Python, run nuget install pythonx86 -Source $(Get-Location) -OutputDirectory target\installation\directory
