Hi,
Did you install with EZ-install? If so, the Box location has the file WQDevWork230_HFx.exe that you can download to your PC and run to install Developer Workbench. Otherwise, Peter is correct that the path /qibm/proddata/qwebqry/DeveloperWorkbench will the .exe and .rar files that you can download and run.
