I am running Linux and with the recent 1.3.3 upgraded revision, I was getting an error on launch. I went to the folder where my Eve game files are stored and simply deleted the folder containing that version. Then the program fell back to 1.3.2 or 1.3.1 and it repaired itself by installing the 1.3.3 revision.
I won’t promise that will fix the launcher, just easier to delete one aspect than to reinstall the whole game.
