Creating a VB on Windows 7-32bit for Windows 8-32bit

[c3p0i]

Tried to run a VB Windows 8.1 (32 bit) on my Windows 7.

Encountered the following errors:

1. Failed to create the VirtualBox COM object.

The application will now terminate. Callee RC: E_INVALIDARG (0x80070057)

2. Failed to open a session for the virtual machine Windows 8.

The virtual machine 'Windows 8' has terminated unexpectedly during startup with exit code 1 (0x1). More details may be available in 'C:\Users\c3p0i\VirtualBox VMs\Windows 8\Logs\VBoxStartup.log'.

Result Code: E_FAIL (0x80004005) Component: Machine Interface: IMachine {480cf695-2d8d-4256-9c7c-cce4184fa048}

I have attached the *.log with this ticket.

Thanks and Regards.

Looks like there is a DLL RocketDock.dll which should be mapped into the VirtualBox process. That DLL is not signed, therefore VirtualBox refuses to start.
