Unzip, move the YTOOLS folder to C:\YTOOLS, add C:\YTOOLS\fas to Trusted Locations and the Support File Search Path, add YTOOLS-LOAD.lsp to the Startup Suite, restart AutoCAD and type YLICKEY. The README in the download walks through it in about 3 minutes.
Both. YMENU opens a launcher grouped by category; YTBAR adds five icon toolbars (Text, Dim, Piping, Draw, Misc). Every tool also works as a plain command.
Each key activates on 2 computers. Moving to a new PC: run YLICCLR on the old machine, then YLICKEY on the new one.
