Error REGDB_E_CLASSNOTREG (0x80040154)

Hi

The host is Windows 7 Ultimate.

I'm trying to start another Windows 7, which was working just fine before I installed and Android emulator called Droid4X.

I get this error: Failed to open a session for the virtual machine WIN.

I click on Details, and it says,

The virtual machine 'WIN' has terminated unexpectedly during startup with exit code 1 (0x1). More details may be available in 'C:\Users\Orion\VirtualBox VMs\WIN\Logs\VBoxHardening.log'.

Result Code: E_FAIL (0x80004005) Component: MachineWrap Interface: IMachine {f30138d4-e5ea-4b3a-8858-a059de4c93fd}

Anyone, will you help me please?

Thanks. Could you try again with the most recent Windows 5.0.x testbuild (revision 106583 or later)? It contains a fix for a problem visible in your log file. If your VM still not starts, could you attach another VBoxHardening.log? Thank you!
