But it's just THE ONLY ONE Linux distrubution that works EXACTLY LIKE WINDOWS.

Now I need someone that explains me how to "install" the -rt kernel on UBUNTU STUDIO ...

Anyway... open a terminal window in the directory which contains the executable file (the directory will likely be called "amd64") and then in the terminal window, type:

sudo chmod +x "Pianoteq 5"

Now you can test if it runs by just typing:

"Pianoteq 5"

(remember the TAB key is your friend in the terminal ) ...you'll see any diagnostics messages in the terminal window.

On a side note, there are no ".exe" files in unix systems. So-called filename "extensions" are dos and windows's deficient way of trying to tell different formats apart by adding a 3-character property that shows up at the end of the filename. This comes from a Unix "tradition" of indicating file types by adding a suffix to the filename, but in real systems, nothing "binds" the file to a specific type based on the filename. This case is an example, where in windows an executable filename HAS to end with ".exe", whereas on Unix systems (including Linux) there's a specific flag to indicate a file is executable, you usually control these with the "chmod" command. (there is no "chmod" command on dos/windows) Anyways, there are many other filename shenanigans and complications we have to thank bill gates for, but for today that will be all.

I did unpack all those files successfully, but the Properties box does not indicate where the .exe files links to (though I can figure that out, I think).

As I said, this happend when I installed Pianoteq on another computer. Eventually it dawned on me why it was't working, but I can't remember what  the reason was.

I seem to recall this happening when I made a previous installation on another computer, but I can't remember how the problem was resolved.

Anyone?
