That nets me the installshield exe which gives the same error, but i was able to get the msi by running the exe from the command line with the /x flag, and copying it from temp before selecting anything, but it looks like it has to be launched by the initial install shield exe, as it errors out saying that the wizard was interrupted. Was also able to find the drivers in the temp folder too, it seems it has an issue running the installer rather than extracting for some reason. Running the controlvault fw upgrade util after copying drivers it was complaining about gives an error of not being able to detect controlvault, and now i remember seeing sharpie on the board when swapping the cpu yesterday.
I'm guessing the board was swapped with one that didn't have the chip (if it works that way, I'm not familiar with these high end dells) and they left the old palm rest with the two readers in place, seems I'm out of luck unless I can track down a board with it, or find the ic and solder it on myself
