virtualbox.org

When I open VirtualBox Main Menu and press setting buttom after selecting any stopped Guest Machines.

I will receive a warning message like below figure.

2.2.0, 2.1.x and 1.x.x does not have this issue.

How can I do to fix it?

[Configuration]
OS: Windows Vista Ultimate x64 SP1
VirtualBox version: 2.2.2

Try reinstalling VBox as administrator and select the repair function. Reboot the host and see if this fixes the problem
