Still no dice.
FYI, this is on a fresh install of OP, patched, OP+4.0, then SG04. (actually, it's a copy of a 3.4 installation, that uninstalled, then 4.0 installed, with SG04. Yes- the latest one. Only the scripts are missing)
I didn't have a previous installer or old GW files as I saw mentioned somewhere. I checked the completed installation list of the SG04 installer, and it didn't list those scripts I listed earlier here. Did a login check, still reports the same missing files.
