Was able to get NV to install on a laptap. I ubuntued a desktop and have been trying to install it there, but running into problems. The install finishes with:
Now, I was able to do 'start.sh', but it crashes when tryng to play the game, so I figure something didn't get installed right.
Those messages are normal (just processing the game icons & icotool skipping irrelevant data in the icon files).
What exactly happens when you run the game (open a terminal in the wrapper directory and run start.sh from there to check the terminal output)?
Also what are the system specs and which Ubuntu version are you trying to use & have you installed the system's Wine package to ensure that you have all required dependencies?
If you're using an Nvidia GPU you should install the proprietary drivers; otherwise you should make sure that your kernel and Mesa are up to date.
