Our registration process opens a small, Internet Explorer-based window which communicates with the license server. If the registration window did not open, that typically means there is a problem with Internet Explorer on your system or security software is preventing the opening of the window.
Please open Internet Explorer, and go to the following website:

Note:You cannot activate via this page. We just need to know if it opens and looks like our registration window.
