What do you mean by "start it with c"? Do you mean start it using the Windows path (i.e. C:\)? I tried that and got the same message. I don't understand why it is not giving any errors; it doesn't even attempt to start. I have never had any application that would not give some errors in the terminal if it didn't work. I tried running it like: seth@linux-allj:~> wine start 'C:\Program Files\TrueGames\Mytheon\launcher.ui.exe' And it gave the fixme error: fixme:exec:SHELL_execute flags ignored: 0x00000100 But from my understanding fixme errors aren't very serious at all.
