This message appears after quitting then relancing GD.
I can certainly turn around this, installing GDevelop from Web site of GD but
this is abnormal situation.
This happens when the update is interrupted.
In summary, this is what happens:
You open GD
10 seconds after launch, GD detects an update.
If you have auto-update enabled, GD downloads the installer for the next update in the background.
If auto-update is Off, nothing is downloaded, and you won’t get the update as desired.
You close the app to get the update, but at that precise moment, because you closed GD, auto-update launches. Therefore, the installer is updating GD where you installed it.
You relaunch GD, but the installer had not finished its installation. It can take 5-20sc depending of the computer.
You have an app that no longer works because the update has been interrupted when you started the app.
That mean you can’t launch the engine anymore and have to download again the app by ourself.
