This is almost always a problem with Wasteland 1 trying to launch at a resolution your monitor does not support. To resolve this you will need to do a small amount of file editing:
- On Windows 7/8/10, go to %localappdata%\inXile entertainment\Wasteland\wl.conf (to do this you can go to Windows Explorer/Computer and type in the directory in, or run a Windows search for wl.conf)
- Press Enter to open the file in Notepad (if Windows asks you to open the file with a different program, please be sure to select Notepad)
- Find the line "fullscreen=true" and change it to say "fullscreen=false"
- Save the file by going to File -> Save in the menu bar, then try launching Wasteland 1 again.
This should fix the problem and get the game running.
