Diamond Download Area

This page is the central access point for the download of the current version 5 of Diamond. There are separate download areas for previous versions of Diamond in the navigation bar on the left side of this page.

Download Diamond Version 5.0.0

Diamond version 5 is distributed as a self-extracting executable file (*-Setup.exe). It is provided with online-help, a user manual, a tutorial, a small structure type database as well as several sample files. A special version of the Crystallography Open Database (COD), dated April 2021, is available separately here as ZIP file for download.

The software package provided below can either be used:

1. to install the Diamond demonstration version,
2. to install the Diamond full version for the electronic delivery option,
3. or to install an updated version 5.0.1, 5.0.2 etc. (when available), if you do not use the "automatic online update" function.

The download package contains a general license file that lets Diamond run as demonstration version only. In order to turn Diamond into a full version, you have to obtain a special license file that you typically receive per e-mail when you purchase a software license for Diamond with the "electronic delivery option". (The special license file will replace the general license file with the instructions provided with this e-mail.)

Please note: The Diamond 5 user manual consists of several HTML files. The tutorial file (in the previous Diamond version 4 called "User manual") is recommended for users without experience with Diamond. In any case, you should read the What's New article, available by the corresponding command in the Help menu.

Diamond Demonstration Version

Restrictions of the demonstration version
The Diamond demonstration version is identical with the full version except of the following restrictions:

• No saving: Changes in structure documents cannot be saved in the original file formats of Diamond 3, 4, and 5 (the Diamond Document format, "diamdoc") and the Diamond Structure File format ("DSF"), which has been used by earlier versions of Diamond.
• Banner: A banner with "Diamond Demonstration Version" will be written into saved bitmaps, Windows Metafiles, and printouts.

Registration
If you are interested in the free-of-charge demo version, we would appreciate very much if you register for our mailing list. Although this is not mandatory for downloading the software from below, we would like to be able to inform you by e-mail when updated versions have become available.

Uninstall Diamond 5 Preview version

Important note for users of the Diamond 5 Preview version
If you installed the Diamond 5 Preview version, you should first uninstall this preview version. Otherwise the installation of the release version will fail with an "Another version of this software is already installed on this computer ..." message.

Download and install Diamond 5

We recommend to read the file "Readme.txt" before you install Diamond. There you will find details about system requirements and instructions for installation.

Please note: Diamond 5 uses a special license file (yourlicense.lic) that works only with this version. Diamond 4 users should not overwrite this license file with the license file that they use with a purchased license of Diamond 4! (License files are not compatible.)

Using Diamond Version 5 with a Diamond Version 4 License

Since the update of Diamond version 4 to 5 is free-of-charge, customers of Diamond version 4 can use their license file ("yourlicense.lic") for the new version 5.

Versions 4 and 5 can be used on the same computer, because they use different sub-folders of the "C:\Program Files" or "C:\Program Files (x86)", rsp., folder, where Windows installs software by default.

In order to replace the demonstration license file delivered with the installation package with your purchased Diamond version 4 license file, do the following:

1. Before you start the installation after successful download, make a backup copy of your license file "yourlicense.lic", which is located in the Diamond version 4 program directory, by default: "C:\Program Files\Diamond 4" or "C:\Program Files (x86)\Diamond 4".
2. If you do not want to keep Diamond version 4 on your computer, you can now uninstall your current Diamond 4.x version. Please note that this removes the executable and data files as well as your Diamond version 4 license file from the Diamond 4 program files folder. (Your personal/latest Diamond 4 settings keep stored in the Windows registry.)
3. Install Diamond version 5 (which contains only the general demonstration license file).
4. After successful installation re-copy your backup copy of the license file into the Diamond 5 program directory (by default: "C:\Program Files\Diamond 5" or "C:\Program Files (x86)\Diamond 5") in order to enable the full functionality of version 5.
5. Afterwards, please run Diamond 5; your license data should now be displayed e.g. in the splash screen as well as the "Help / About Diamond" window.

Crystallography Open Database (COD)

A comprehensive version of the "Crystallography Open Database (COD)" is available for the Diamond software, amongst them data from "American Mineralogist Crystal Structure Database" (AMCSD) as well as from International Union of Crystallography" (IUCr) journals.

In this context, we would like to thank Pete Strickland (IUCr), Armel Le Bail (COD) and Bob Downs (AMCSD) for their kind permission to download and distribute their data free-of-charge!

Due to its size, the COD is no longer part of the Diamond installation package. The COD delivered with version 5.0 of Diamond consists of several Diamond database files basing on the April 15, 2021 version of the COD and contains approximately 471,000 entries with a total size of 8.4 GB. Updated COD versions will follow later during version 5.x of Diamond.

If you want to use the COD through the File/Search command of Diamond, you must first download and unpack the Diamond-specific version of the COD (27 DIAMBASE files in a ZIP file) from here:

COD installation instructions
The Diamond 5 installer creates a "COD" sub-folder in your Diamond program directory (which is by default "C:\Program Files\Diamond 5" or "C:\Program Files (x86)\Diamond 5"). This contains only a "Readme.txt" file with a short installation remark and a hint to this page. You should place the DIAMBASE files into this "COD" directory. (Note: You need administrator rights to put these files into a folder or sub-folder of the Windows programs directory.)

1. Click on the download link above. This will start downloading the ZIP file into the default folder "Downloads" on your computer. (Alternatively, you can right-click the link and choose the "Save link as" command to choose a different folder.)
2. Extract the DIAMBASE files from the downloaded ZIP file into a temporary directory.
3. Move the DIAMBASE files to the target folder.
4. Diamond automatically recognizes if the DIAMBASE files are completely in the "COD" sub-folder of the Diamond 5 program directory when you start a search with the File/Search dialog.

If you do not want to place the DIAMBASE files into the "COD" sub-folder of the Diamond program directory or have no administrator rights, you can place the files into a different folder. In this case you must tell Diamond where to find the DIAMBASE files:
a) Run the command File -> Search. (This first throws a warning message that the COD files have not been installed or the target folder has not yet been set.)
b) After closing the warning message, the Search Files dialog comes up, where you click on the Search criteria button.
c) In the File Search Options dialog click on the Database path button to choose the folder containing the DIAMBASE files.
Note: The sub-files of the COD are listed in the upper part of the dialog. The sub-files are accessible, if there is no "[n/a]" suffix at the end each.

POV-Ray

Like the previous Diamond versions 3 and 4, the new version 5 can use POV-Ray to create photorealistic pictures. If you would like to do so, please download and install also the POV-Ray software package:

Download POV-Ray (povwin-3.7-agpl3-setup.exe)
[31,273 KByte]  January 31, 2017

Please note:
(1) The POV-Ray editor (to edit, change, render, and debug POV-Ray 3D scene files) uses a different license type and is thus not included in the above mentioned software package. The last step in the installation procedure will point you to a POV-Ray web page where you can download the POV-Ray editor from. We strongly recommend to install this editor, too, even if you do not intend to edit or debug POV-Ray scene files. Otherwise you will receive a prompt whenever Diamond starts a POV-Ray rendering job and the command "Tools/POV-Ray/Launch Environment..." fails or shows an auxiliary POV-Ray window where you cannot edit the POV-Ray scene file.
(2) You should run POV-Ray separately before you make the first POV-Ray rendering job from Diamond. Otherwise Diamond may have trouble locating the POV-Ray executable "pvengine[64].exe" on your hard disk.
