I also have tried a very simple workbench csv to csv like below

and i get this error :

CSV reader: Failed to open file 'C:Usersg-lamiDocumentsWorkbenchCSV.csv' for reading. Please ensure that the file exists and you have sufficient privileges to read it

A fatal error has occurred. Check the logfile above for details

the .tcl file is this one
