NOTE: Before upgrading MultiCHAX, it is recommended that you create a backup copy of your MultiCHAX database before installing a new version (or repairing MultiCHAX).
After you have created your backup, you will need to remove the previous install of MultiCHAX prior to installing the latest version (failure to do so may result in conflicts).
Use your new upgrade serial number during the installation process and point the install to your previous MultiCHAX database folder.
MultiCHAX will automatically update the database files as soon as you launch the application.
