I have read through all the other entries regarding the Data.com assessment app installation for those having issues and cannot find an answer to resolve the insufficient privileges issue. 

When I click 'Get It Now' it lists my username as my correct trailhead playground username (of which I am a system admin) however after clicking Install it continues to ask me to 'Log In' to Salesforce - As I dont have a password for my trailhead version it keeps wanting to install on my production org.

Can anyone please assist?
