unable to upgrade drivers of intel wireless 6235

hi all,

like the object i'm unable to update the driver and the software of my win7 64bit from 15.3.1.0 to 15.6.1.0 like suggested from intel driver update utility.

I tried also to execute the file but i have this error .

" Error detected during install : 80070002

Please resolve the error and retry installation "

I tried to install manually files and so on but wothout success. Now the drivers is updated (to 15.4.1.0) but not the software..

I need last version because i need to test a WiDi new device that required the last driver & software.

Please help me.
