I can't find that for EULA's proper (would surprise me, too, as that would allow anyone to pirate any shrink-wrapped software), but EULAs cannot prohibit selling your license: that was upheld for software bought by download, too: http://curia.europa.eu/jcms/upload/docs/application/pdf/2012...:

"Where the copyright holder makes available to his customer a copy – tangible or intangible – and at the same time concludes, in return form payment of a fee, a licence agreement granting the customer the right to use that copy for an unlimited period, that rightholder sells the copy to the customer and thus exhausts his exclusive distribution right. Such a transaction involves a transfer of the right of ownership of the copy. Therefore, even if the licence agreement prohibits a further transfer, the rightholder can no longer oppose the resale of that copy"

You can even buy the right to download future updates:

"Therefore the new acquirer of the user licence, such as a customer of UsedSoft, may, as a lawful acquirer of the corrected and updated copy of the computer program concerned, download that copy from the copyright holder’s website."
