'DynamicTransform' could not be found while generating a CustomScaffolder by T4Scaffolding

I am trying to use T4Scaffolding for my current project but it fails at the beginning.

I do step by step same process on this link that teaches how to use T4Scaffolding for a basic console application.

Steps that I did

1- I created a new console application (.NET 4.0)

2- I installed T4Scaffholding successfully by using package manager console (install-package t4scaffolding)

3- I tried to create a demo custom template by using package manager console like

Scaffold CustomScaffolder T4Demo

then it throws the exception below

Add-ProjectItemViaTemplate : c:\Users\ryu\Desktop\SpiderWeb\ConsoleApplication2\packages\T4Scaffolding.Core.1.0.0\tools\CustomScaffolder\DefaultPs1Script.ps1.t4(1,48) : error CS0246: Com

What am I doing wrong ?

Solution

After I changed my windows regional setting from my native language to USA, the problem has gone. Do not forget to restart Visual Studio.

really annoying problem !
