Oracle VM VirtualBox crashes after 'shutting down' Windows 8 with guest additions installed.

I'm having the following after installing 4.2.18. It will run when installed, and I check the box to run after the install but after I reboot it won't run and I get this:
Failed to create the VirtualBox COM object.
The application will now terminate.
Callee RC: E_NOINTERFACE (0x80004002)

If I reinstall VirtualBox-4.2.14-86644-Win it runs ok.

Well, it didn't take long to figure out. I installed virtualbox as admin and it ran with admin rights. When I run the app with admin rights it opens fine, I'm not sure why that changed in this version but that's the fix.

I get a blue screen crash in windows 8 64 bits host when connect an USB device to virtual machine. Get DRIVER_IRQL_NOT_LESS_OR_EQUAL(VBoxUSBMon.sys) error. VirtualBox 4.2.18. All guests: Xp, Ubuntu. The problem is when connect usb in menu "Devices - USB Devices".

On 4.2.18 under Mac OS host, the Linux guest VM crashes when I do most anything with a USB device. USB sticks don't work at all. Other USB devices sometimes work, but always after I plug in a USB device and access it via the Linux guest, a crash will occur in the VM.

This is really quite bad. I liked the idea of VirtualBox and hoped to transition away from Parallels. From what I can tell, VirtualBox itself is pretty good but the host tools for 4.2.18 make the product unusable for me in a professional setting.

Why are you talking about a Mac host in the "Windows Hosts" forum?

In fact this entire thread seems to be a redundant duplication of the function of the v4.2.18 discussion topic. Locking this one.
