Right click or CTRL-click on the link. Drag down to something like "Save
Link Target as..." or "Save this Link as..." or "Download
Link to Disk" or "Download Linked File As..." or "Saved
Linked File to Desktop...".
You will need a way to unzip the file/folder. You can place the resulting file/folder anywhere.
Each program has a "Check for updates" menu item that can tell you whether you have the latest version.
Programs should work on Windows 8-11. If you get a message about a missing dll, run Windows Update.
Programs should work on Mac OS 10.14-14.x (Mojave, Catalina, Big Sur, Monterey, Ventura, Sonoma). Since the Mac OSX applications are not signed, you will need to control-click the app icon and choose Open from the context menu the first time you run it.

iORTEP - A Crystallographic Plotting Program
To plot a crystal structure you need to enter
values for
-the unit cell dimensions (axes in Ångstroms, angles in degrees),
-the space group symmetry (equivalent positions and centering),
-a unique name, fractional coordinates, and thermal parameters for each atom.
