Python For Windows 7 64 Bit

cybersage78

I've been trying to set up Python on an older machine running Windows 7 64-bit, and I'm running into a few hurdles. I'm aware Windows 7 is no longer officially supported by Microsoft, but I'm hoping to get it working for some lightweight scripts.

Python Version: Which version of Python is best to install on Windows 7 64-bit for compatibility and security? I understand Python 3.9 is the last version to officially support Windows 7, but would an earlier version be more stable?
Installation Issues: During installation, I encountered an error message about missing DLLs. Has anyone else faced this, and what did you do to resolve it?
Dependencies: Are there any specific Windows updates or dependencies I need to have in place before installing Python on Windows 7?
Alternatives: If Python 3.9 is too much for this system, is it worth considering using Python 2.7, even though it's no longer supported? Or are there lightweight distributions for older systems available?
Security Concerns: Running an older OS and potentially an unsupportive Python version brings security risks. What are best practices to mitigate these risks?

Any advice or shared experiences would be greatly appreciated!

I've worked with Windows 7 in similar situations, and you're right to consider these factors carefully. Here's some advice based on what I've experienced and researched:

Python Version: While Python 3.9 is the last to officially support Windows 7, I'd recommend staying with it if your scripts need features from Python 3. Otherwise, Python 3.8 might be slightly more stable on older systems due to it being out longer with more resolved bugs.
Installation Issues: The missing DLL issue often relates to the Visual C++ Redistributable for Visual Studio 2015-2019. Make sure that's installed as Python requires these dependencies. You can download it from the official Microsoft website.
Dependencies: Besides the C++ Redistributable, ensure your Windows 7 is updated with the Service Pack 1 and any subsequent updates still available. This enhances compatibility for newer applications.
Alternatives: Python 2.7 could be lighter, but is significantly outdated with no security updates. A safer lightweight alternative might be using a distribution like Anaconda or Miniconda, where you can manage environment versions including Python itself.
Security Concerns: Security is a valid concern. Consider isolating the machine from sensitive networks, regularly updating any security software, and possibly using a dedicated virtual machine with better security measures for Windows 7.

I've been in a similar boat before trying to get Python working on older systems like Windows 7. Here’s what I’ve learned along the way:

Python Version: Sticking with Python 3.9 is a good choice since it's the last version supporting Windows 7. If you're not utilizing newer features, Python 3.8 might offer slightly better stability. However, with fewer updates, security could be a concern with older versions.
Installation Issues: The error related to missing DLLs is pretty common and usually comes down to needing the Visual C++ Redistributable. Make sure the one for Visual Studio 2015-2019 is installed on your system. This package ensures you have the necessary runtime components required by Python.
Dependencies: Besides the Visual C++ Redistributable, it's essential to have your system updated with Service Pack 1 and any other crucial updates. These will improve compatibility with newer software.
Alternatives: Python 2.7 is generally not recommended due to its end-of-life status, which means no more security patches or updates. Anaconda or Miniconda can be a lightweight alternative, or even something like PyPy if performance is crucial and you're okay with some compatibility issues.
Security Concerns: To mitigate risks, ensure that your system is isolated from critical networks and use comprehensive security software. Running the scripts in a virtual environment can also help keep your main system safer.

I hope this helps, and if you need more detailed instructions on any of these steps or have other questions, feel free to reach out! How have these steps worked for others in a similar situation?
