JChem for Office works with the standard Chemaxon licensing infrastructure, and also allows several points of extension. If additional license files are specified, JChem for Office takes into consideration all of the licenses. Since JChem for Excel (JCXL) is part of the JChem for Office (JCO) package, the JCO license is valid for JCXL as well, but the JCXL license is not appropriate for JCO. When installing JCO you can decide if you want to install it together with JCXL, for more information, see Installation.
The default location of the license file (license.cxl) is:
C:\Users\<current user>\chemaxon
For more information regarding licensing, see the following pages:
It is possible to use the following JChem for Office features without having a valid license:
Visualization of structures in JChem for Office documents.
Printing out JChem for Office documents.
Running the license form and license settings.
It is always advised to install the latest released version of JChem for Office or JChem for Excel, which can be downloaded from Chemaxon's website:
If you have only JCXL (without JChem for Office) it is advised to uninstall your current version from your computer first. Locate the software in Control Panel > Programs > Programs and Features and then uninstall it.
If you previously had JChem for Excel but currently purchased a JChem for Office license, please uninstall your current version from your computer first.
If your JCO license has already been installed in one of the four products (Word, PowerPoint, Outlook, OneNote, Excel), it will be valid in all other three products. So, license installation has to be done only once.
