I have an interesting problem. There is no ai vector generator. It is neither in the right panel or in the Window menu or in Contextual bar. I have the latest version of Illustrator, and I'm not in China)
I am not familiar with a feature called “Vector Generator” in Illustrator. Can you show something that mentions this? If you mean autotrace (convert bitmap image to vector) then look in Windows > Image Trace. If something else, please elaborate.
