Hi, I'm quite new to this VirtualBox, but I have a library of every Windows edition (1.0 Premiere - 10) and None of them seem to be working, they opne up the guest window, and then it closes instantly! The Message it displays:
Failed to open a session for the virtual machine Windows 10.

Unable to load R3 module C:\Program Files\Oracle\VirtualBox/VBoxDD.DLL (VBoxDD): GetLastError=1790 (VERR_UNRESOLVED_ERROR).

Result Code: E_FAIL (0x80004005)
Component: Console
Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

this happens no matter what I do! I have tried reinstalling, making new Guest Operating Systems and nothing seems to work, Hope you can Help me!

Try it with VirtualBox 4.3.12, and try reading the "Security" discussion stickied at the top of this forum.
