Right click on the application itself and you access at the hidden directory where you can find the two files. The location are in the redepic_importer_install_cs6.pdf file.
For Premiere Mac :
*For the ImporterREDServer.app :
*Applications/Adobe Premiere Pro CS6/Adobe Premiere Pro CS6.app/Contents/
For the ImporterRED.bundle
*Applications/Adobe Premiere*Pro CS6/Adobe Premiere Pro CS6.app/Contents/Plug-*‐ins/Common/
There are probably to many informations on the pdf. Just be sure to place the 2 files at the right place. Of course, an auto installer should be better, but I prefer to do it manually than to wait 1 or 2 monthes more just for such an easy installation
