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).

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, this 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 a better generation of animated gif files than the latest one. 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.
