"Failed to start Trigger for Task on behalf of specified user"


The error indicates that a Trigger could not be initialized on behalf of specified user, namely, using that user's access credentials. Being a part of a Task, the Trigger is run in the Windows user account that is provided in Task properties Run As tab.


Possible reason for failure of Automation Workshop to start Trigger is that either domain, user name or password is entered incorrectly in Task properties Settings tab or such account does not exist. Verify that domain, user name and password is specified correctly and enter correct values in Task settings.


It is strongly recommended to use 32-bit Automation Workshop version on 32-bit Windows machines, and 64-bit version for 64-bit Windows machines. If 32-bit Automation Workshop version is mixed with 64-bit Windows or vice versa, the following error may occur: "Failed to start Task on behalf of specified user. The data area passed to a system call is too small. [os:122]". View all downloads to download correct version.
