How Do Call Winzip From Execute Process Tasks?

Hi,

In my ETL project, l need to extract rawdata using winzip, and the DOS command l use is
c:program filesWinzipwinzip32.exe -min -e c:
awdata est.zip c:
awdata
where -min for minimize and -e for extract, c:
awdata est.zip for source file and c:
awdata for destination. It works fine by using DOS command.

l configure the Execute Process Tasks with the following parameters, i.e.
RequiredFullFileName : TRUE
Executable : c:program filesWinzipwinzip32.exe
Arguments : -min -e
WorkingDirectory : c:program filesWinzip
StandardInputVariable : User::gsRawFile
StandardOutputVariable : User::gsDestDir
Where User::gsRawFile = c:
awdata est.zip and User::gsDestDir = c:
awdata

But it can't work....no error return.

Any idea when l make the mistake?

Thanks.
