I have the latest video drivers on my host. I just confirmed. I went into Safe Mode & removed the Additions & booted the system back up & installed the Additions again when the system was fully up. I still have the same problem.
However, now when I go into the settings for my guest (while it's off) it tells me "Invalid Settings Detected", but it doesn't tell me where or what the problem is. How do I figure out where the Invalid Setting is?
Just to be clear, my host is Windows 7 Pro 64-bit & the guest is Windows 7 Pro 32-bit. The guest is set to use 4 Processors, but I can't change it due to the "Invalid Settings Detected" message.
I don't understand the question:
Which VGA Card has the host, which vga driver is installed on the host?
Do you mean, what VGA card does my host have? - I have an Intel i3 so I'm using the built in Video & the host is using the Aero settings fine.
