• OS: Windows 11 x64
• Python: 3.11 32-bit
• Pillow: 10.1.0 (any 10.x.x)

Since Pillow 10, 32-bit wheels are no longer provided:

https://pillow.readthedocs.io/en/stable/releasenotes/10.0.0.html#bit-wheels

Is there a reason you're using 32-bit Python on 64-bit Windows? Can you re-install with 64-bit Python?

[radarhere]

Pillow should still work on 32-bit, you just have to build it from source yourself. See https://pillow.readthedocs.io/en/stable/installation.html#building-from-source for more information.

If you like to read more about the decision to no longer provide 32-bit wheels for WIndows, see #7443.

Is there a reason you're using 32-bit Python on 64-bit Windows? Can you re-install with 64-bit Python?

Yes, actually, I have some clients who still use old systems operating on Windows 32 architecture. Therefore, I can't transition to 64-bit Python to continue providing support for these clients. The obfuscator binds python interpreter to executable, so, If I bind python 64-bit version, only 64-bit OS will run executable.

Sure, I understand the reason not to maintain support for 32-bit, as this architecture is becoming obsolete. I prefer using Pillow 9.5 version, which has the necessary installation wheels.

In the future, I may build this from source for an upgrade, but I don't currently have the need to use the latest version.

Thank you for your response, and I appreciate it! You can close the topic.

Pillow 10.2.0 has been released, now with Windows 32-bit wheels once again, so you should no longer need to downgrade.
