First, start up torrent. Accept whatever you have to accept. Once torrent starts up, right click the sro loader (Only if its 100%) and click open containing folder.
To minimize lag, close torrent when the folder comes up.
Now, the killer part.
When you double click the blue window file that says sro_global, it would normally freeze. Right click it for the drop down menu. It will freeze the window up. Wait for about a minute or 2 and possibly more. Eventually the icon for the installer will come up. Now right click it and click open.
It will tell you to 'Please Wait...'
Wait a couple minutes. It might take longer.
Soon, it will ask for access to the internet through your anti-virus and firewall programs.
Then, the main window will come up and you can click install.
Hope this helps
