Can we just install Omni Price on 1 workstation and 1 server, rather than all of our workstations and servers?
Yes, you can install Omni Price on specific workstations and servers without installing it on all of them.
Omni Price is installed on a specific company database in addition to the Dynamics database. So, if you had multiple companies you would be asked if you would want to install it on the additional company and that should only happen on the workstations and/or servers where it already exists.
