no, that's what i mean.  it does not do that.  S4 writes that line.  as i said, i already searched for "082."  i didn't even do the whole name, just to be sure.  there's nothing about any of those channels anywhere in the base V4 install on its own.  and if it does update that line, that's just stupid and annoying (on DAZ's part, not yours), because the S4 installer could do that just fine.  and aren't we supposed to update the V4 base first?

this is all that's in the V4 base install:
    readScript ":Runtime:libraries:!DAZ:Victoria 4:head:05-ps_pe069_DAZ_Chnnls.pz2"
    readScript ":Runtime:libraries:!DAZ:Victoria 4:head:05-ps_pe069inj_Chnnls.pz2"

seriously, i've looked through all of the Body files, most of hip and head, and spot checked other parts. so far, there's absolutely nothing that has anything to do with S4 before S4 is installed. nor any evidence of the other add-ons.
