I poked around at this. Unfortunately, you need i386
binaries for all the dependencies. There's quite a list of these, and you even need to install the GTK+2 binaries, which are generally bad. As well, the Linux launcher has a crash issue and crashes every time you try and use it, on 14.04. This renders it unusable.
However, I had found another option. There is much more smooth and better functionality in using the Windows standalone flash projector with Wine. You can do this by installing wine
and then using the Windows projector .exe
file. I suggest you use that route, as it is more smoothly-operable, and doesn't crash.
