This is a bug caused by some changes to internal stuff. Hope it's fixed soon!

This is because the 3.9.0 version requires the 64 bit hardware and CPU. 64 bit CPUs can run 64 bit software.
3.6.0 does not need that much.

Oh! OK

This is the right idea:
First, I have a Idea as if we see in 64-bit Scratch Downloaded PC you see many files in C Drive then Program Files Folder then Scratch Desktop Folder right-click then click on Properties option then the size of the file in 64-bit windows is large from 32-bit windows! So if you move them all files 64-bit to 32-bit then search the main file on start menu, You can run it properly because Microsoft doesn't want to give everything in 32-bit windows! So if anyone can so please share the files not setup in github and provide the link here then everyone can download on 32-bit PC!

I uninstalled Flash Player because it takes data on my PC and no longer supported!
