Hi,

I would like you to clarify whether the new editor and mod related features - or any features for that matter - will be Steam only. You have to make the game the same on GOG as on Steam. I understand that you cannot add Steam workshop to GOG, but there should then be a supported alternative. Otherwise, you are basicaly encouraging people to not buy the game from GOG in the future. This is unfair to both the players who bought it here and to GOG themselves.

Is it also supposed to work with the offline installer ? I can't manage to make it work.
Always get a "Data export failed" message...

That's nice. I think it's a path problem. there is alteady a problem with the launcher : GOG's offline version can't be launched by selecting GOG in the launcher, we must take the 3rd option beside Steam and GOG, I don't know how it's called in English (edit : it's "launch with custom path"), and the mod toolkit have a log file about path errors, but I'm not sure of the problem, I'll try again tomorrow and post the log file here.
Since it's a new laptop it might also be a redist problem, but I'll be able to try on my desktop computer on the next week end.

Here's the content of my log file :

Thank you, I'll try that as soon as possible and let you know if it work.

No, it still doesn't work. Strangely, the log say it's ver. 1.0.17, but I downloaded it today from your link (edit in windows installed apps, it say 1.0.19 correctly).

Here's my log, GOG forum won't let me post the txt file, so i'll copy the content :
