为何系统老是坏掉,有人遇到这种情况么?

E:>boot2docker status
error in run: Failed to get machine "boot2docker-vm": fork/exec C:\Program Files
\Oracle\VirtualBox\VBoxManage.exe: Access is denied.

E:>boot2docker init
error in run: Failed to initialize machine "boot2docker-vm": fork/exec C:\Progra
m Files\Oracle\VirtualBox\VBoxManage.exe: Access is denied.

E:>boot2docker up
error in run: Failed to get machine "boot2docker-vm": fork/exec C:\Program Files
\Oracle\VirtualBox\VBoxManage.exe: Access is denied.

要崩溃了:(

Edit 1:
用的就是管理员权限啊,不行

刚重启可以运行,不过之后就没法运行了,咋回事?
