Big trouble installing NS

[Doobie Dan]

I got a new computer set up last week  <3  but I'm having trouble getting NS installed.  I first installed HL from the disc, then tried to install NS3.  Realizing my error, I then installed Steam, and tried to install NS again.  Realizing my error again, I activated HL1, went into a game there, then quit, and tried to install NS again.  This time it should have worked, but I think something from the previous installs are messing things up.  The install goes through its motions, says its successfully installed, but it never appears on my games list (Third party games isn't even a choice list in Steam).

I've been through the instructions in the Tech Support forum about installing.  It doesn't matter how many times I try, it goes through successfully, but never shows up in the list.  Does anyone have any suggestions?

where's your NS folder?

steam\steamapps\email addr\half-life\ns is where is *should* be, if it's not showing up there the installer didn't work properly.

Scrape your computer clean of all old NS installs and try again.
