Hi,
No, this is not a bug. The "Extraction Location" field from "Media->Bootstrapper" page represents the location where the MSI, CAB files are extracted from the EXE file in order to be executed. By default the extracted MSI, CAB files are deleted after installation unless the "Do not delete extracted MSI and CAB files" option is checked.
So to delete the extracted MSI, CAB files after installation leave the "Do not delete extracted MSI and CAB files" option unchecked.
Regards,
Gigi
