Package Customizations
Your previous Arbortext Editor installations might have customizations of files in the Arbortext-path\packages directory. Many of the files in the packages subdirectory change from version to version, so you should compare the contents of your customized files to the new files.
You might want to add your customized .acl and .js files to the Arbortext-path\custom\scripts subdirectory.
* 
Customizations specific to a document type should be moved to document type command files (doctype.js or doctype.acl) or document type instance command files (instance.js or instance.acl) within the custom\doctypes\doctype directory.
Refer to Using the Custom Directory for more information.
