virtualbox - I can't open Virtual Box on windows 10 after the Microsoft update on 9/21/2016 -


i can't open virtual box on windows 10 after microsoft automatic update on 9/21/2016.

i error vagrant up:

bringing machine 'default' 'virtualbox' provider... ==> default: checking if box 'scotch/box' date... ==> default: clearing set forwarded ports... ==> default: clearing set network interfaces... ==> default: preparing network interfaces based on configuration...     default: adapter 1: nat     default: adapter 2: hostonly ==> default: forwarding ports...     default: 22 (guest) => 2222 (host) (adapter 1) ==> default: booting vm... ==> default: waiting machine boot. may take few minutes... guest machine entered invalid state while waiting boot. valid states 'starting, running'. machine in 'aborted' state. please verify configured , try again.  if provider you're using has gui comes it, helpful open , watch machine, since gui has more helpful error messages vagrant can retrieve. example, if you're using virtualbox, run `vagrant up` while virtualbox gui open.  primary issue error provider you're using not configured. vagrant issue.

trying start vm windows app , nothing. no errors, no vm

does else have problem?

is there way update vm on windows re-installing?

this worked me, finally, though don't think long term solution.

uninstall virtual box delete .vagrant directory (..../vagrant/.vagrant) re-install virtual box version 5.0.20 (this older version) vagrant

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
