Fatal exception "Bad Conversion"

Postby Raderim » Wed Apr 25, 2018 9:50 am

Hello.
I have a little problem. I use the flightgear version 2018.1.1 , and when I press the "FLY!" button message appears [Fatal exception "Bad Conversion"]. How I can fix it?

you cannot... we need to see the log file to determine the actual problem, though... since you posted in the windows area, i'm guessing your using winwhatever... with that in mind, click on your start button or whatever they are calling it these days... in the white field that appears, type in "%APPDATA%" without the quotes and hit the enter key... a folder should open up... look in it for the flightgear directory... in there you'll find fgfs.log... post it to some place like pastebin and give us a link... you might post it here in a message if it isn't too big (<40k IIRC)...

"Why not?" said Gurder.

are you sure that's the whole log?
where'd that "GOG" and "Galaxy of Games" stuff come from??

i'll pass this on to the dev mailing list... i can't see anything wrong but someone else might... i can't even find the string "bad conversion" in the FG code... the only time i find that phrase is in openscenegraph and it is related to LUA which FG doesn't use, AFAIK...

I've been having the same problem, but with 2018.2.2. Did anyone fix that error? Thanks!

@andrepaoletti: Could you also provide the log file contents? That would help track down the issue. It would be better to copy and paste the content here within

We need some more information to fix this, since it's only happening for certain people. Besides the log file, it would be helpful to know if there's anything unusual about this system: - in terms of home directory, drives, timezone, language settings etc.

[Bad-English]
I had the same issue since 2018.1 . I just fixed it, but I don't know, if it's helpful for you.

(I have my Scenery-folder in my Flightgear-directory "\FlightGear 2017.3.1\data\Scenery"and made it my Download location in FlightGear-settings)
I copied the ,,AI"-folder from "\FlightGear 2017.3.1\data" into the Scenery-folder in "\FlightGear 2017.3.1\data\Scenery" and it worked. I hope you understand what I did, if not, just ask me. :D

@SquabToast: Are you able to unfix it? I'm guessing some of your version numbers are incorrect: you say "since 2018.1", but then you have a "2017.3" FGData folder? But the FGData version and FlightGear version absolutely must match. The information you give unfortunately does not allow us to reproduce the error. I would suggest having a read of the following for what type of information would be useful:
