I have tried multiple ways of manipulating the shockwave installer - however even after I get shockwave installed, it doesn't actually activate. I believe it's because Safari is using a 64bit...
Hey there!
I just wanted to warn those who are running Mac OS with a fresh install, that if you try to install Shockwave it will not be compatible with Mavericks. For the time being it appears that the software version is incompatible on their installer.
