Upgrade and Uninstall

    If you would like to install a newer version of JChem for Office on your computer, first you have to uninstall the previously installed version manually.

    To uninstall the program, navigate to Control Panel > Programs > Programs and Features.

    {info} During the uninstallation process, the User Account Control (UAC) settings are turned off to avoid constant notifications about the registry changes. This is normal and after the software is uninstalled, the settings are changed back to the original state.

    If any Microsoft Office applications are still running during uninstallation, the user can either close the applications or continue without doing so (in which case, a reboot may be required)

    If you have different Chemaxon products installed on your computer, please, make sure that they have the same released version.
