 ===== Downloading PyMOL =====
-PyMOL is a complex bit of software and requires some other libraries which we need to install.
+PyMOL is a complex bit of software, but someone has assembled it to work on Windows for us (thanks [[https://www.lfd.uci.edu/~gohlke/|Christoph Gohlke]]!).
-  - From the [[https://www.lfd.uci.edu/~gohlke/pythonlibs/#pymol|PyMOL]] section on the Gohlke page, download the file ''pymol‑2.3.0‑cp37‑cp37m‑win_amd64.whl'' in directory ''C:\pymol_installation''.  You need to create this directory first from Windows Explorer.
+  - From the [[https://www.lfd.uci.edu/~gohlke/pythonlibs/#pymol|Pymol-open-source]] section on the Gohlke page, download the file ''pymol‑2.4.0‑cp39‑cp39‑win_amd64.whl'' in directory ''C:\pymol_installation''.  You need to create this directory first from Windows Explorer.
-  - Under the [[https://www.lfd.uci.edu/~gohlke/pythonlibs/#pymol|PyMOL]] section on the Gohlke page, also download the file ''pymol_launcher‑2.1‑cp37‑cp37m‑win_amd64.whl'' in directory ''C:\pymol_installation''.
