Hello,
After downloading Fallout New Vegas and started the game this lead me to the launcher this all appeared fine till i actually clicked "Play" this came up with the error "Fallout: New Vegas does not appear to be installed and the installer could not be found, try exploring to your DVD-ROM drive and selecting setup.exe to install the game". well as this is on steam i do not have the DVD and when exploring the folder in which all the files are located i found no actual "FalloutNV.exe" only the icon and launcher. i have re-installed this many time and it has no effect. please help

Problems in short:1 try to play, error: "Fallout: New Vegas does not appear to be installed and the installer could not be found, try exploring to your DVD-ROM drive and selecting setup.exe to install the game"
2 re-installed many times no effect.
3 no "FalloutNV.exe" in folder.

thanks for your time

Anything in your event viewer? Do you have the german version?
