How do I open .ai files on Windows 8.1?

Specifically this file

Flux / Vague de Dollars - Illustration - image | Adobe Stock

I tried to rename the file with .pdf extension, but FoxIt would not open it.

I tried to install Inkscape but it would not open it either.

I tried to convert from .ai to .png with FFMPEG, but it gave an error ".\AdobeStock_35571058_WM.ai: Invalid data found when processing input".

I need to convert it to PNG format.
