I forgot to mention that you can also delete dcom95.exe, dcom98.exe, and dcm95cfg.exe if you are only installing on Windows NT, 2000, and XP. Also, if you will not be using any database features, you can delete Mdac_typ.exe. This will further reduce the size to 28 MB (these numbers are for TestStand 2.0.1, it might be more or less for other versions).
