Upon opening a console window in VS12 (rtm)  - MVC4 project

Exception calling "EnumerateFiles" with "3" argument(s): "The path is not of a legal form."
At C:\Users\foo\package
s\MvcScaffolding.1.0.7\tools\init.ps1:23 char:45
+         | %{ [System.IO.Directory]::EnumerateFiles <<<< ($_, "*." + $extensio
n, [System.IO.SearchOption]::AllDirectories) }
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException

something specific to my installation or compatibility at the package level?

I'm getting the same thing in version 1.0.8 .
