On the workstation throwing these errors, run the following command:
"C:\Program Files\Altiris\Altiris Agent\AeXAgentUtil.exe" /registerclient
This should register the .dll's needed for the agent to start. You can also push this command out using Deployment Server or Login Script. It may also be possible to get Task Server to run this command if the Task Client is started, but as a precaution to you, this has not been tested by support and may not work.
