I see. There is a workaround though. Just follow these steps:
1. Download the portable Viewer
2. Unpack the downloaded archive to your local disc.
3. Run the rutview.exe in the folder and populate the address book with records - either manually or (if you already have an address book file created in a different Viewer) use the Tools -> Import Connections command. Close the Viewer.
4. Distribute your folder to whatever machines you want to run Viewer on and run the Viewer executable whenever you want to run the Viewer (you can create a shortcut on Desktop just like for any other file).
I'm assuming that you are using the General address book. In this case you don't have to touch the Address Book Manager at all (it's in the Tools tab).
However, if you want to create a separate address book alongside the general one, you'll need to add one more step. Namely, to add a relative link to your address book file in the address book manager. See this thread https://www.remoteutilities.com/support/forums/forum1/437-problem-using-portable-viewer
Let me know if you have any questions. Thanks.
