The above described error message is typically seen if the Scheduled Updates account, the default scheduledupdates@Spotfiresystem or the custom account used if used, is not part of Scheduled Update Users group. So to resolve, make sure to add the scheduledupdates@Spotfiresystem account, or the custom user account if used, into the Scheduled Updates Users group. The session for the Scheduled Update User is only created when the Web Player starts up (and is then kept alive as long as the Web Player is running), so you have to restart the Web Player Instance to make a new attempt with new settings in place.

Also, make sure that this user have the needed library access to open the files and all other dependencies.

• Grant Browse+ Access permissions on folder(s) where analysis file(s) are saved that needs to add in scheduled update
• Grant permission to access folder(s) that saved information link(s) for these analysis file(s).
• Grant permission to access folder(s) that saved Data source(s) for these analysis file(s).

This article will help you resolve if a TIBCO Spotfire Web Player instance throws an error message "The configured scheduled updates user is not a member of the group 'Scheduled Updates Users'".
