So what, if anything, is the difference between the retail and the NIS-bundled version? And what I mean is from an installation / registration point of view, not functionality. I've gotten the install to work by creating a server image followed by silent install through msiexec: msiexec.exe /i "Path\to\Norton Ghost 9.0.msi" symsetup=1 reboot=reallysuppress /q* It still asks for the serial on first run, though. And after that symlcrst.dll doesn't appear to have changed (though its datestamp is updated daily). I haven't tried backing it up and reinstalling my system (I did that just last week, only without Ghost; I did install NIS2005 silently with a symlcrst.exe like in Astalavista's thread), and I'm really not about to just to test if it will work... so if anybody has experience with this?
