I thought you were trying to execute custom commands on the FTP Task. Obviously you are using the Execute Task. Sorry for that misunderstanding.
I think one problem might be that it runs in another context than usual. Please try to set a Credential, then one you are normally logged in as, in the Execute Task. Because, if you don't specify anything your command will run as SYSTEM which may affect environmental settings, security and things like that.
Also, think about which working folder you want to use. If you execute a command the working folder will be the same folder as your command - but perhaps you want the working folder to be: C:\transfers\EEP\?
I don't know, but this might be differences that cause this to fail.
If you tried the above - and it still fails we would like to know all details about your Execute settings. Best way would be if you exported your settings in VisualCron and sent to email@example.com
