The Preflight with PitStop task fails with these messages in the task log:
Error 2450: General Exception
C:\Esko\bg_data_cms_v010\r\icc\ISOcoated_v2_300_eci.icc: General Exception
ERROR: PitStopTask.Message.Failure
Symptoms
All the files will fail as long as the Color Management checkbox is enabled and a specific color profile is used from the Lab drop down list.
Solution
The selected color profile is not a Lab profile. So it should not be selected in the Lab drop down list. You need to select an appropriate Lab color profile.
