GrassGames

I get problem installing the software. There is a specific procedure I have to follow? thank you in advance.

You need to extract the zip file somewhere on your system and then double click the 'Free Solitaire 3D' file you will see there to start the game.

I do so but when i click a pop up appears saying "an error occurred"

and also with the licensed version

Linux is tricky as systems can be quite different. Do you think you can run it in the terminal and get the logs here?
Hopefully opening a terminal and dragging the file there then pressing enter in terminal will do that.

mari@mari-lubuntu:~$ cd Solitaire3D/
mari@mari-lubuntu:~/Solitaire3D$ Solitaire3D
Solitaire3D: command not found

mari@mari-lubuntu:~/Solitaire3D$ Solitaire3D

That's a warning so does not look like the problem.

Try typing "./Solitaire3D" from the same folder instead of just "Solitaire3D". Also try "./Solitaire3D.exe".

You can try that, and then you can start the game using "mono Solitaire3D.exe" as far as I can remember. It might help to get "./Solitaire3D" working also. Sorry, I don't have a Linux OS handy at the moment to verify, and only did previous testing on Ubuntu.
