It is not possible to use the ESEA client while Hypervisor is enabled. We understand that some users need to use Hypervisor for work-related reasons but we are unable to make any exceptions and it must be disabled in order to use the ESEA client.
How do I disable Hypervisor?
All you need to do is open an elevated command prompt (run as administrator) then type the following:
bcdedit /set hypervisorlaunchtype off
bcdedit /deletevalue nointegritychecks
After that just restart your computer and your Client should load as expected.
If you are part of the Windows Insider program this can also cause this to occur and you must roll back to the released version of Windows as the ESEA client is not compatible with beta builds of Windows.
