To download Anaconda with Python 3.7, follow these steps:

1. Visit the Anaconda distribution page at https://www.anaconda.com/products/distribution.
2. Choose the version that suits your operating system (Windows, macOS, or Linux).
3. After choosing the correct operating system, look for the Python 3.7 version. If the latest version doesn’t support Python 3.7, you can find older versions in the archive section.

Please note that, as of my knowledge cut-off in September 2021, Anaconda might not continue to support Python 3.7 as the primary Python version because newer versions are available and more prevalent. Therefore, it would be better to use a more recent Python version if possible.

However, if you really need Python 3.7, consider using an older version of Anaconda that specifically supports Python 3.7. This version may not be available on the main download page, so you may need to look into the archive versions.

I’d recommend checking the official Python and Anaconda documentation for the most up-to-date instructions.
