SQL job "COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046}"

I have a sql 2008R2 job set up to execute an ssis package to retrieve results from a mailchimp web service and output an Excel report.

When I run the job manually,it succeeds. When the job runs with schedule time if fails with the below error.

I have the job steps set to run with a proxy user.

Can any shed any light on this?
Is there a reason why the job succeeds when can run the job manually, but fails on the schedule time?
