Opening file from newer version with doubleclick gives no error message, it just doesnt open

[11011100]

Scenario: File1 created with Treesheets V1 on PC1 File2 created with Treesheets V2 on PC2

File1 opened on PC1 File2 opened on PC1, via Open... dialog in Treesheets => Warning appears that File2 was created with a newer version and doesn't open => Minor problem, user can install newer version

File2 opened on PC1, via doubleclicking in windows explorer => No warning, Treesheet opens last used file (here File1) => User doesn't know why file isn't opening

I dont know I this has already been fixed with the newest version. Happend when trying to open a file created with 2019 Version in a 2017 Version

Yeah it should at least show an error dialog before exiting.
