Activation of apps impossible due to Norton

Hi All,

I am a new member on thisd forum and hope someone could help me.

My daughter's pc is running Windows 8 and Norton intyernet Security.

I installed wysiwyg web builder and it is impossible to activate it probably because Norton blocks the internet access.

 

As I do not know Norton, can someone tell me what to do to open internet access for this apps ?

 

Thanks a lot
