Cannot type on path Photoshop 7.0

Been trying for weeks to type text on a circle. I've done everything i should - create the shape (ellipse), ensuring that the path option is selected, then when I click on T (for text), nothing happens, no matter where I hover.  The cursor does NOT change shape to that squiggly line.  I've tried inverting the path, trying the add, subtract, intersect, exclude options - NOTHING works, whenever I try to text, it types text in a horizontal line.  I'm going bonkers here.  ALL the tutorials say that the minute I have the path up there and click on T, and hover over the line of the path, it SHOULD change shape to the squiggly cursor so I can type.  It doesn't.  Someone said that Photoshop 7.0 specifically doesn't work with typing on a path, but I can't believe that.  I'm using a windows computer, windows 10 (although I'm sure that has nothing to do with it).
