I cannot install the language pack CDs for Rosetta Stone.

Question

I'm trying to install the language packs of my Rosetta Stone package. The application CD installed ok, and it is running. You need to then install the language CD from inside that application. When I "add language CD", I get the error "You must have administrative permissions to use this feature." I've set all permissions for all groups the "read & write" on both the Rosetta Stone app file and the content folders. I've called Rosetta Stone and they tell me this is an Apple problem. Help please! I'm getting really, really frustrated with this!
I'm on an iMac, OS X 10.9.5
Thanks.

Frank,
so, I did search for the directory Language Training - it doesn't exist on my system. As an experiment, I manually added the directory and gave it read/write permissions. Rosetta still couldn't install the language CD. I've cut and pasted the permissions below of the Rosetta Stone directory as well as the bin directory. I wonder if I'm having this problem because I'm trying to install Rosetta Stone Version 3? That is the latest version that allows for homeschooling.

next I'm going to try installing it from a user (non-admin) account
