Using Admin privileges, on the desktop I have dragged three Id-Extras scripts into the Scripts folder, but they don’t appear in Window / Utilities / Scripts in InDesign. What am I doing wrong?
What is the path to the Scripts Panel folder? There are two (Application and User), and perhaps in InDesign’s Scripts Panel you’re not looking in the correct folder?
Are you sure you’re dragging them into the Scripts Panel folder of the correct version of InDesign? Perhaps you’ve got 2 versions of InDesign installed and you’re dragging them into the wrong version?
