I'm running Linux Mint and an application called anki (flash card app). The software repositories for Linux Mint are a few versions behind. When I download the new program it just runs from the directory. The problem is that when I launch it from the menu it opens the old version, not the new. I placed the folder in /usr/share/anki-1.2.9/, the old version is located in /usr/share/anki/. I tried replacing /usr/share/anki with the contents of anki-1.2.9 but then it wouldn't launch.
What I'm missing is how to tell the system to use "/usr/share/anki_1.2.9/" instead of "/usr/share/anki/" when the command, "anki" is executed. I'm fairly new to Linux but I'm sure it's something simple like editing a file in a directory somewhere. I just have no idea which file and where?
