IE tester, con IE9

Para comprobar mi página web en todas las versiones de Internet Explorer, @Quintin Lippiatt me sugirió un programa gratuito, IETester que lo hace de maravilla. Le falta la versión de IE9, puesto que no han seguido desarrollando dicha aplicación. Aquí copio un pequeño tutorial de cómo añadir manuealmente el IE9 a nuestro IEtester.

Also note that IE9 Preview requires Vista SP2 or Windows 7 to install on the machine.

Starting with IETester version 0.4.3, IE9 preview can be integrated into IETester by following those install steps :

1. Install IETester version 0.4.3 or newer version.
2. Install IE9 preview (click on "Install the Preview" button from this page)
3. Open two explorer windows. On the first window, go to C:\Program Files\Internet Explorer Platform Preview\ folder, and on the second window, go to C:\Program Files\Core Services\IETester\ie9 :
4. Copy the folder iepreview.exe.local from C:\Program Files\Internet Explorer Platform Preview\ to C:\Program Files\Core Services\IETester\ie9 :
5. In the C:\Program Files\Core Services\IETester\ie9 folder, rename the folder iepreview.exe.local to ietester.ie9.exe.local :
6. Done ! You don't even need to restart IETester, the IE9 button should become active after a few seconds.
