automatic installation cannot continue ??? cant reinstall my norton netbook editino 2010

hi i just purchased the edition 2010 version of the norton programm.

I set up my pc new and now im trying to download the nortoninstaller file again through my norton account.

after download i get a popup window that the automatic installation cannot continue.....and i have to klick on a button where is mentioned how to install this product. I did that but basically i can just download the installer file again, what i already did.....but i can not start this installer because of this popup message.

can anyone help ?
