I'll take another look, but it is working for me.
Hmm...well that's good! I wonder what's going on on my end? I will keep tinkering. I think I'll start from scratch with everything. Companion, the Installer, and NSIS
Damn! I just downloaded/reinstalled new versions of Companion, the Publisher, and NSIS, merged the foldres and am getting the same result...very frustrating!
I cannot seem to get it to produce a script at all, for any game I put in, whether I press "publish" in companion or "NSIS publisher." All the project properties are auto-filled just as you said, but when I click "publish" nothing seems to happen. If I click the NSI script editor tab, there is just a blank page.
