Yes, but with caveats.
Team Cherry did release 32-bit executables for Hollow Knight during its early launch window. Specifically, versions 1.0 through 1.3 contained 32-bit support. The GOG (Good Old Games) version, known for its DRM-free philosophy and preservation of older executables, retains access to these legacy builds. If you purchase Hollow Knight on GOG today, you can navigate to "Extras" and download the offline backup installer from 2018, which includes the 32-bit binary.
Steam users are generally out of luck. By version 1.4 (the "Lifeblood" update), the Steam backend had fully transitioned to 64-bit only. There is no launch option or beta branch to revert to 32-bit via Steam.
You have three viable paths to explore Hallownest on your older rig.

If your PC is too weak for cloud streaming, consider the original hardware. Hollow Knight runs on:
None of these require a 32-bit Windows PC.
Let’s say you upgrade to 64-bit Windows 10, but your PC is still weak (e.g., Intel Atom, Celeron, or early i3 with integrated graphics). Can you run Hollow Knight?
Yes—surprisingly well. Hollow Knight is legendary for its optimization on low-end 64-bit systems. Yes, but with caveats
Minimum 64-bit requirements (real-world):
Tips for low-end 64-bit PCs:
Players have reported stable 60 FPS on Intel Atom x5-Z8350 tablets (64-bit) after tweaking.
Paper: "Analysis of 2D Game Engines and Development of a Cross-Platform Game" ⚠️ If you see “out of virtual memory”
First, a quick technical primer. A 32-bit operating system can only address a maximum of 4 GB of RAM. While Hollow Knight is not a VRAM-hungry AAA monster, its later areas (like the Queen’s Gardens or the intricate particle effects of the Colosseum of Fools) benefit from memory headroom. When the game was initially released in 2017, 32-bit builds were still common. However, as Unity engine updates rolled out and the player base migrated to 64-bit systems, support for the older architecture faded.
Why does this matter? If you try to run the standard Steam version of Hollow Knight on a 32-bit machine, the OS will simply refuse to execute the code. You won’t get a crash or a stutter—you’ll get a hard "This app can’t run on your PC" error.
