I have not fired up my old Windows 7 machine and tested this but hopefully it will address this issue. UPDATE: In the next update of CSS HTML Validator 2022, it should set the NODE_SKIP_PLATFORM_CHECK environment variable to "1" if using Windows 7. Please let me know if the above works if you try it.

This is usually something like C:\Program Files\HTMLValidator220\Node.js So my suggestion on your Windows 7 machine is to download Node.js v13.6.0 (either the 32-bit or 64-bit version should work) and replace the node.exe file in the Node.js folder in CSS HTML Validator's installation folder.

I've read that Node.js v13.6.0 is the last tested (with Windows 7) version:

If you must use Windows 7, then you can try using an older version of Node.js, like v13: So it looks like the version of Node.js that comes with CSS HTML Validator 2022 is not actually Windows 7 compatible.
