I downloaded the .exe for my Vista x64, it decompresses the 2 .msi installers, and when it tries to install either CAL or Brook+ it launches a Message Box that says:
Installation ended prematurely because of an error.
I am sure I download the x64 version and that my Vista is x64, I've got the SP1 and I have administrator privileges. My GPU is the HD 4850 and I've got both 2005 and 2008 VC++.
Do you know why I can't install it?
Please feel free to ask any further details, thanks for your help.
