Thank you very much for your reply.

I tried to look for the version you have, but I can't seem to find it on the eclipse website.
Could you perhaps please share a link so I can also get the latest beta version?

I have the exact same issue.

I am using Eclipse IDE:
Version: 2020-12 (4.18.0)
Build id: 20201210-1552

and the Preprocessor Include paths menu item is no where to be found.

Attached is a screen shot of my menu.

Can anyone help?
