No portable Evernote version because there is no permission from the publisher:
On http://portableapps.com/node/22217 there have been created portable versions of Evernote developed under the PortableApps.com format and for use in the Portableapps.com Platform. But the developers had no permission from the publisher to repackage the freeware. So unfortunatelly the link to the illegally packaged software had to be removed by mod JTH. But many people need a portable Evernote version, which can be executed on a DropBox-, TeamDrive- or USB-stick-folder. People, who have no admin rights on their business computers must use PNotes Portable or CherryTree portable until now. Because NixNote is Open Source it should be legal to make a portable NixNote version.
