Error received from Edge Agent: An error occurred trying to start process

We have been unable to open attachments in Kinetic, the edge agent is attempting to open the wrong file path and I am not sure where this can be updated. Any help would be greatly appreciated.

Have you checked in Attachment Path Maintenance? There is also Attachment Type Maintenance.

Yes, everything seems to be in order for the Attachment Path Maintenance.

If mapped drive letter rather than actual server path confirm the mapped drive letter is available on client PC?

What do you mean by wrong path? Give an example.
Also what is in Edge Agent log?

See screenshot for example of mapped drive letter vs actual server path. If a mapped drive letter is referenced in Epicor Attachment Path Maintenance, rather than the full server path, then confirm the client PC also has the mapped drive letter. Something to double-check.

looks like it is set in Document Type maintenance, check it there
