The Windows Phone Emulator wasn't able to create the virtual machine: Something happened while creating a switch: Xde couldn't find an IPv4 address for the host machine.
I have SLAT compatible hardware, virtualization is enabled in BIOS, my Windows 8 installation is 64bit and it's not virtualized. Hyper-V is installed (tried reinstalling it, but it didn't help). EDIT: VirtualBox or any other virtualization software (except for Hyper-V) is not installed
EDIT2: Seem to have been some other networking software which was installed. Having to remove it sucks big time because I need it professionally. I hope they fix it.
