I tried this and I found that after clicking the "Save Settings and Close" button in the "Element ID Manager" Dialog, a folder called
EIDM Settings <AC version>
will be created in the following folder:
The folder contains the Element ID Manager (EIDM) Settings file, which has a *.bin extension.
You should copy the folder to the same locations in the other computers you want to use. You will probably want to restart ARCHICAD just to make sure it reads the latest version of the file during startup.
I think the folder is ARCHICAD version-specific so there will be multiple folders if you are using multiple ARCHICAD versions.
