I received "Installation FAILED" with code 7?

This probably means you have problem with Internet connection to reach our license server.

I received "ERROR CODE: install_httperror/7" or "install_httperror/52"?

This probably means you have problem with Internet connection to reach our license server. It could also mean our license server is down temporarily, as sometimes it might happen under DDoS attack (but it should resume shortly).

You may want to check other Internet site (such as Google or Yahoo) to see if your Internet connection is working normally.
