I also had this problem but found that it was a glitch with the NuGet package manager. Although my package sources were defined (the default nuget.org and an internal nuget gallery), I had to de-select, click 'OK', then reopen and select the sources again. After doing so the 'restore missing packages' option succeeded. This was a very frustrating glitch and oddly only affected one of my VS2010 solutions!

Found problem. Source for NuGet was not set by default in visual studio 2012.

In package repository does not exists one/many of project requiring packages. We have local nuget repository and after getting project to new PC it was impossible to restore missing packages, because they was old and only newer version of those packages where exists in repository.
