DS 7.6 (HF4) - Tasks in automation fail on predefined computers

Hi,

I am testing automation with DS 7.6 (HF4) and it seems like it is working fine if I use existing computers however if I have a predefined computer all tasks fail to run.

I receive either the following error messages within the automation (smp.log):

CAtrsException exception, error = "Unable to find class ID", OS error = 2147746291, at line 69

CAtrsException exception, error = "Failed to execute task", OS error = 2147746291, at line 535

Or if I try to schedule a task / job from the console I receive the message "This device is not capable of running this task".

Has anyone else seen the same problem or has anyone seen this working?

Stefan
