Why I’m can’t run gdevelop games on 32-bit Windows PCs? Maybe Electron don’t support 32bit, yes?
GDevelop does not officially support 32-bit operating systems in any form, not just Windows.
The online service will not compile to 32-bit, but you might be able to locally compile for 32-bit, but you’d need to have an understanding of Electron and whatever compiling method works for your machine.
That method would be unsupported however, so we can’t offer you much guidance here.
