Hi,
I am also a node.js & web developer.
Scratch Developers Forgot to mention that scratch 3.0 can be used on windows 10

Usually when building scratch, the .exe file will be made to run on that specific OS version and above,
Scratch developers have build and signed it on windows 10.
Hence we can't use it on win7

But since scratch is open source, you can build your own scratch 3.0 file for your os!
(There is nothing special that scratch 3.0 needs from windows 10, it works on windows 7 also)

If you are not a developer Download from here, The website Uptodown have built scratch 3.0 from win7, hence it works for your win7 even!
As said If you are not a developer then you have to trust the non-official company - Uptodown

But if you are a developer, Then you can build your own official(as of you) version.
Remember not to distribute what you have built as your own! Use it only for personal purposes!

Yeah… this is totally not yet another sketchy download site.

Using windows 7 in 2022 is a terrible idea. Instead of downloading this random program from a random website that may or may not be a virus, you should probably switch to an operating system that is being updated.

I would like to know what kind of errors. I am curious, I thought that older Scratch 2 used Flash.
