Hi,

Probably permissions problems.

under what user the service is running?

Does that user has permission to read the source and write in the selected
directory?

 

[Jay]

yes user has all the permissions to carry out execution.

Hi,


How the output is produced? does it generate a file? are you passig the
fullpath for this new file?

Are you getting any exception?

Also check the exit code of the .exe
