If you don't mind using the portable versions of the larger apps like Blender, you can install the PortableApps.com Platform on your local hard drive and install and update all of those apps in a couple clicks. (Our portable apps work just fine locally, they just won't appear in your start menu by default, you have to add a shortcut manually or launch them using the PA.c Platform) Apps like Blender, Inkscape, GIMP, LibreOffice, GnuCash, Scribus, Firefox, Thunderbird, etc.
