- the linux web player is broken atm, opening firefox will do you no good.
- the official installer for the standalone player does not add the binary location to $PATH, at least it never worked for me. the unofficial community installer does that
http://www.stonetrip.com/developer/forum/viewtopic.php?f=35&t=21711&start=15#p30505 , but it has other shortcomings and will not run everywhere (no fedora for example, no 64 bit distros). so in order to run your stk with the standalone player, open a terminal and run "/the/path/to/shiva/binary yourpack.stk" or do a small script/shortcut for user friendliness.
- you can also just drag and drop your stk over the standalone player binary without installing anything.
