same issue here. I have the GTL installed from raceroom but when I'm trying to install HistoriX 1.9 and they ask for the raceroom.zip file I cant find it. Even pointing the SIMBIN/GTL folder, it did not work.
do you have the 'old' digital download provided by Raceroom (the one which was downloaded as a .zip file which contained a couple of .exe files) or did you get the game on Steam ( forwarded there from Raceroom site)?
I've send my GTL CD's photos (since my CDs are invalid/risked/not functional) to the racerrom staff and they've provide me the KEY for the GTL. So I've downloaded the digital version from raceroom. Its located in C:\Program Files (x86)\SimBin\GT Legends
It works just fine but I cant manage to install HistoriX, even pointing that folder.... I dont have any raceroom.zip file neither the GTL installer that I've downloaded. I think I've deleted it to get more free space disk.
