COM Error: 80040408
From Zymergi SupportPI ProcessBook, you may encounter a persistent COM error with non-informative description:
- COM Error: 80040408
- description =
Often, this will be with the PI BatchView objected embedded.
This error is due to the DEFAULT SERVER parameter on the user's computer that tells PI ProcessBook (or other PI Client Tools) to which PI Server to send requests. Because this is a configuration issue at the user's computer, the error happens for some individuals and not others.
To resolve this error, go to File > Connection then Tools > Options
Connection Options window will appear. Ensure that the DEFAULT SERVER is set under Default Server Settings.
There may be an Override option for current user. In some cases, this needs to be set as well. To be thorough, set this as well.
