We deploy a Win7 64bit English version with 6 diffrent MUIs via SCCM 2012 CU1.
And we also deploy the IE9 64bit EN in the same Task Sequence after the OS MUIs has installed.
Update KB982861 (Windows Internet Explorer 9-LP for Windows 7) is also installed on our systems.
It doens't matter which Language we've set the IE9 is always English.
What are we doing wrong?
