12 years ago I'm experiencing this same problem when trying to install MvcMailer using NuGet package manager in Visual Studio 2012 RTM on Windows 8 RTM. It tries to install T4Scaffolding 0.9.9 when there's already version 1.0.6 out there: http://nuget.org/packages/T4Scaffolding.
https://github.com/smsohan/MvcMailer/blob/master/Mvc.Mailer/NuGet/MvcMailer.nuspec
I looked the file's code and T4Scaffolding is 0.9.7. I really don't know why NuGet tries to install version 0.9.9... The way it is it should grab the most recent version of T4Scaffolding.

MvcMailer sends emails using the MVC views as Email Body with no effort. Here's a quick list of features: a) Use Razor/WebForms views b) Use Master pages c) Write Testable Code d) Pass values to your view using ViewBag or ViewModel and e) Generate Absolute URL using Url.Abs method and f) create multi-part emails by just adding a view file, g) scaffold your mailers.
MvcMailer has a MailerBase class that extends ControllerBase class. So, Mailers are just like your Controllers. As a result, you can use all the controller goodies without any learning curve, period. The end result is a professional looking HTML email body ready for your to send to your website users.
Visit the Project site for a comprehensive tutorial on MvcMailer.
