I tried VBox 3.0.10, build 54097 (PUEL), when I became aware it had become available today (that was around 10:00 am German local time (GMT +1), but to no avail. Needless to say, that I did boot my computer after each attempt to install / uninstall VBox, or USB-Drivers.

I´m using a guest with Win 7 RC 32 bit (no 64 Bit RC available). Hardware is a Core 2 Quad Intel CPU (Q8300) with 2,53 GHz and 8 GB RAM. Just upgraded from Vista Ultimate 64 bit (German edition too) where all was ok. Reach us via the feedback form below for any questions or comments.I was running VirtualBox 3.0.8 (same problem with 3.0.6 and now with 3.0.10) on a Windows 7 Ultimate 64 bit host ( German edition, though the forum-posts show the same problem for users of English editions too). You can now install a 64-bit operating system in your VirtualBox. How to Configure Network Between VM and Host in VirtualBoxĬongratulations!
