I got the notice that a new version of SIW is available.  Today I tried unsuccessful to install it.  I started the  process from within my current 2014 version and was told that the update was valid and needed.  I downloaded the file and when I ran it, I got two errors.  The first error was from Windows saying that it could not access the specified device path or file and that I did not have permission to do so.  I attempted to run the file normally and as an Administrator.  I am the administrator for my computer.

Secondly, my Symantec SEP SBE flagged the file as harmful and  deleted it. 

I would appreciate any help.
