NIS 2011 - How to get the installer without installing?

Is there a way to just get the installer without installing it?  The instructions above seem to imply if you let the NISDownloader.exe get started that you just bought a one way ticket to upgrade?

 

Thanks.

 

Anyone care to post a description of "what's new from 2010"?  In particular, I am curious if anyone was done to improve on NIS 2010's aggressive SONAR2 deleting of files.

 

Thanks.
