This is probably caused by antivirus blocking the installer. Disable it during the install.
So I have Norton 360 and I disabled the firewall so that the download could go through. However I received the same message as before. Exact wording as follows: T3A:Online for BFME2 Setup Wizard ended prematurely because of an error. Your system has not been modified. To install this program at a later time, run Setup Wizard again. Click the Finish button to exit the Setup Wizard. That was exact wording. Is it possible I did not disable the antivirus correctly? Please let me know.
