JADEK  A couple days ago I installed 32-bit Vista Home Premium w/SP1 on my 2008 MacBook (Leopard 10.5.4) with 4GB of RAM. I did a clean install under Boot Camp to a 32GB partition.

I got the notice for BootCamp 2.1 and tried a live online install. It crashed.

I then DL'd the executable. It wouldn't install. It would just hang part way thru and wouldn't cancel. I had to kill it with Task Manager. I activated Vista's hidden Administrator account and tried again from there. Same results.

After thinking about what I observed during my attempts with the .EXE install file, I decided to try again, but this time with my Mac OS X Install Disk 1 inserted in my DVD drive. This time the install did not hang and I thought I heard a couple of accesses of the DVD during the process. I note the update does not say anything about having the DVD installed. Could the installation have been a random success?

My experience with Vista is that it will not shut down completely after some use. If I wait for the shutdown process to end on its own I get the BSOD (Blue Screen of Death) and the msg Driver_Power_State_Failure and a dump of the error to disk. I have also gotten the same BSOD after bringing Vista out of sleep mode. I have not yet tried to analyze the error dumps, but I suspect a driver problem still exists even with this update.
