virtualbox.org

Hi, i would like to install virtualbox on windows 10, but when i click install, it says another installation is in progress. Why? I have tryed on Virtualbox Beta and Stable but there both the same. Why does this happen. I tryed both versions beta and stable on my other pc (win7starter) and they worked perfectely

That is a Windows message and it usually means just what it says. You cannot start another install/uninstall before the previous one has finished.

Does task manager show anything still running? Have you rebooted the host?
