Latest version of Chemcraft:  

 Version for Windows (64bit):

Chemcraft_b654b_win64.exe     -    Self-installing executable, 21 MB.      -     WinZip archive without installer, 29 MB.    -     Version for 32bit Windows (WinZip archive), 28 MB

Note that the Win32 version of Chemcraft can exhibit some bugs on Windows 8 or Windows 10, unlike the Win64 version. On the other hand, possibly the Win32 version is better for running on Linux or Mac with Wine.


 Version for Linux:

Chemcraft_b635l_lin64.7z     -    7z archive, 13 MB (Linux 64 bit).

Chemcraft_b82_lin32.tar.gz     -     GZip archive, 20 MB (Linux 32 bit, old version of Chemcraft).

Each of these files contains the fully functional version of Chemcraft with the trial period of 150 days. After that period, you'll need to enter the registration key to continue using the software. To obtain the registration key, you can purchase Chemcraft at Order page.

The Windows version of Chemcraft is protected by a third-party anti-hacker software (The Enigma Protector), and because of that, some antivirus programs can produce false positive detection of viruses with Chemcraft. If such problem occurs, you can try alternative versions of Chemcraft (more info).

At this webpage you can try the beta Mac version of Chemcraft (for ARM or Intel).


Newest versions of Chemcraft (potentially less stable)


Old versions of Chemcraft


The .exe distribution is registered in Windows when installed, so for its uninstallation you need to run the unins000.exe file or go to Windows control panel/programs. At the same time, the zip archives should be simply unpacked into new folders, they are not registered in Windows as software, so for their uninstallation you should simply delete the contents of these folders. Maybe it can be a good idea to install several builds of Chemcraft on one computer, because sometimes new versions have new bugs, and old versions of Chemcraft (in particular b405) provide saving gif files with transparent background. Note that old builds of Chemcraft do not run in trial mode (this was a part of our anti-hacker protection), but they run properly in activated mode (after entering the registration key). If you unzip an old build into a separate folder, this will not disturb the work of the main version. With the .exe distributives, a new version of Chemcraft can be installed over previous ones, keeping old display schemes.


Please do not install Chemcraft into "C:\Program files\Chemcraft" folder, this can cause problems.

 Sometimes the Windows version of Chemcraft produces an error - when you open files with it, "The drive cannot be found" message is shown. If you experience this problem, please email to us (some builds of Chemcraft have this problem, some do not have).


Here you can download reduced freeware version of Chemcraft for Windows with several limitations.


You can get the Chemcraft license for free if you help us with the development of the program (more info).

If you work under Mac/Linux and want to use the Windows version of Chemcraft, you should install Wine: here is the installation manual

Wine 5.0 binaries.


  We also recommend using alternative versions of Wine: CrossOver (a paid version of Wine) and Parallels (a paid Windows emulator on Mac).
