When i run this command from terminal / CMD on windows it completes ok

but when I run it from a job in Jenkins it fails

"C:\Program Files\CA\AllFusion Harvest Change Manager\hco.exe" -b BROKEID -usr UserID -pw UserPW -en "Tasks 290" -st Development -vp \ -cp "C:\Jenkins\jobs\Tasks\workspace" -pn "Version Internal" -s "*" -sy -nt -r

The error in Jenkins is:
E03020028: File Agent error for item C:\Jenkins\jobs\Tasks\workspace\harvest.sig : The file is writable

I looked up the error code and it usually means a file name has invalid characters - so I ran it from the cmd line but it runs ok.

Thanks
