Couple things to remember -
When the Pre and Post jobs run, there is no environment and hence no PATH defined. Try putting absolute paths in your PRE/POST job definition
When the Pre/Post job runs, it runs under the context of the BackupExec service account. Try logging on as the Service Account and see if you can run it/them from the command prompt.
if the Pre/Post jobs do require a path (that is they depend on other EXEs or DLLs that are not in the same directory, create a CMD file that contains a PATH command as well as the EXE.Message was edited by:
