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)" defect closed installer VirtualBox 2.0.2 obsolete other Windows
