O2K3 Standard Applying updates

[CelesteNorm]

I have and administrative installation (O2K3) point. I have sucessfuly
applied the update to PRO11.MSI

I used the command below (wich is essentialy the same command for PRO11) to
update STD11

msiexec /a Z:\Office2003Standard\STD11.MSI /q /p
Z:\AdminUpdate\Office2003SP1\MAINSP1ff.msp /l Z:\Update.log

But then it bombs out on me, leaving me this message in the log:

Is there a different update that I should use for Office 2003 Standard? I am
using the same one I updated Pro with.

Thanks,
