Great idea! Where did you get v. 4.1, as it is no longer posted on the Lenovo website?
Based on the number of posts concerning v. 4.2 and Vista SP1, it would appear that the failure of v. 4.2 to install is a "known issue." How can it be that Lenovo keeps v. 4.2 on its website and forces its customers to waste countless hours trying to force v. 4.2 to install? Very poor customer relations.
I phoned customer support and a know-nothing told me that I should reimage the HD on my T60. I told the idiot that I did not have three days to devote to his nonsensical, uninformed suggestion.
