Hello All. Could you please help or at least to give an advice. I'm at first time try to install the Commerce Kickstart (previously I have worked only with simple Drupal 7). On the step of installing demo store, process stopped. Progress bar show 82% done ( install the OAuth Connector module) and it's all. I have wait more then 2 hours and have dropped process. Have re-run setup process a few times with different configurations (with DEMO store, without demo store) anyway the same problem. System stop on the end of demo store installation or on the level of additional modules installation (depend of my chose if I have checked to install demo store or not). What is this, how I can fix it? (of course, before re-run installation process I remove previous, un-successfully installed version of commerce)

I try to install on a MAC (locally) . commerce package version 7.x-2.0-rc4

in case when I chose "use demo store" installation process top on
in case when I not chose "use demo store" installation process top on

Thank you
