Hello Paul,
Thank you for your message.
For your scenario, you can simply use the
Portable Viewer solution that provides the same functionality as regular Viewer but doesn't require installation and stores all files in a single folder of choice.
Alternatively, it's also possible to install regular Viewer on both machines as usual and then set up an automatic update of the address book through a shared folder.
Here's a step-by-step guide on setting up the automatic update of the address book through a shared resource.
However, please note that it's best to use this method if there's only one person who works with the software. For a multi-user environment it is recommended to use the sync server instead. For more information on the sync server, please refer to
this page.
Hope that helps.
