How to install python on Windows without an MSI installer?

Question

My main problem is how can I use python 3.6.12 on Windows?

Since I need to use 3.6.x, I am seeking the latest version available in this branch (currently 3.6.12) to still avail from security patches.

This gives two paths:

install 3.6.8 with MSI installer then update it to 3.6.12 from source,

install 3.6.12 from the source.

What are the measures involved in option 1 or 2?

Answer 1

I think you can create your private MSI installer from the source distributions.

Please be informed that in every distribution, These files:

1. PCBuild/readme.txt 
2. Tools/msi/README.txt 

will provide direction for how to build your own Python installer. If you have not built Python from the source before on Windows, this may be a challenging step to set up.
