offline build

I am trying to build an existing Corona project offline. I authorized my computer, this is the result: 

You have authorized this computer with the ‘Enterprise (Native extensions)’ subscription.

Authorization succeeded.

/Applications/CoronaEnterprise/Corona/mac/bin/CoronaBuilder.app/Contents/MacOS/CoronaBuilder  build --lua args.lua 

Could not launch Corona Builder. Your current subscription ‘Enterprise (Native extensions)’ does not have sufficient privileges.

what is going wrong ? I thought enterprise does enable offline builds?

kind regards

Sven
