I am learning Scrapy, from Scrapy's docs http://doc.scrapy.org/en/1.0/intro/overview.html I input

scrapy runspider stackoverflow_spider.py -o top-stackoverflow-questions.json

and cmd prompt

ImportError: DLL load failed: %1 is not a valid Win32 application.

Details:

Using cryptography version 38.0.4 did the trick!

pip install cryptography==38.0.4

I, too, recently had this problem with OpenSSL on Windows, and in addition to the suggestion of installing pre-packaged library files from https://slproweb.com/products/Win32OpenSSL.html, I also needed to reinstall cryptography.

pip install -I cryptography

I had the same problem. I download and install Win64OpenSSL_Light-1_0_2h and it worked.
