It started running but then I got this
I ran the debug with the command prompt but got this same error can you help ??
I branched your comment to a new thread as it is a different issue from the original thread.
In your case, the online installer appears to be having difficulty communicating with our servers. Please use the standalone/offline installer posted at the bottom of this page Installation problems | Flash Player | Windows. There are two installers, one for Internet Explorer and one for other browsers. If you use IE and non-IE browsers you'll want to install both Flash Player types.
