Centrino 6235 : BT_2.6.1210_e64 and Windows 8 Pro : Hkey_Local_Machine32 error

Hello.

I am experiencing an hkey_local_machine32 setup error using bt_2.6.1210_e64 on Windows 8 pro.

It seems that this release is not compatible with Windows 8, despite of the ambiguous decription of this release.

(Compatible, not compatible ?).

Any idea for a solution ?

Thank you
