VirtualBox installation failure on Windows

错误：When I try to install VirtualBox 1.6.2,
at the end of the installation it says "Rolling back action", removes all previously installed files and then the installation gives me the following message: "Sun xVM VirtualBoxsetup
ended prematurely because of an error. Your system has not been modified. To install this program at a later time, please run the installation again." UAC is disabled, I'm using the Administrator account and the last updates are installed. Computer
is a Intel Core 2 Quad Q9450. I also have tried this on another PC (AMD Athlon 64 3400+, using Vista 64 SP1 too, and it worked fine) I have tried closing at first and even uninstalling later all software that could create issues (Firewall, Antivirus, ...)
I'll include the MSI log (for the little I managed to understand from that it does seem that the issue is an error while installing some drivers)

解决办法：
