I have downloaded the latest Windows support software via Bootcamp to my flash drive while I'm running Mac-OS. The problem now seems to be I can't run the setup program on the flash drive, as it is a Windows program and I'm stuck in Mac-OS. I can't "get to" (i.e. Boot) Windows to run anything on the flash drive. So I have all the drivers (dated June 29, 2011) on the flash drive, but I either can't run them or don't know if there is a Bootcamp program on the drive that will run on Mac-OS and updated all my Bootcamp drivers. After the download completes to my flash drive, I get the message "Install this Windows support software after installing Windows". Not clear on how/when to do this install and the timing (under Mac-OS, under Windows?). Exe files fail as they're Windows files, and not sure if here is a Mac on the flash drive that will do the install. Or can/should I just transfer the files from the flash drive to the appropriate Mac folder, reboot to Windows, and pray keyboard magically becomes unfrozen. I'm thinking I need to find my Win7 install software and set up Win7 all over again via Bootcamp on my Mac. Ugly, but seems to be my last chance.
