virtualbox.org

I am unable to install virtualbox on win xp sp 3. Installer will show progress bar to about 95%, freezes for some time and then rollback all actions and show "sun xvm virtualbox setp wizard ended prematurely".

Is there any log? How should i fix this problem and install virtualbox?

Please see the Forum Posting Guide before you post. That states that you need to search before you post, to see if your issue has been asked before. And it has, dozens of times. Issue is usually the Host Interface, or Bridged in 2.2, driver that causes this. Disable it during setup and it should finish properly. You won't be able to use that network function though.
