Win-Lite Forum

I am using Windows 7 64bit Live CD with portable virtualbox installed. I am trying to run a windows 7 64bit virtualbox on it.

The problem which many of you are familiar with is that the bridged networking is not possible.

If I upload my old working version of VBoxNetFltNobj.dll (taken from portable virtualbox launcher: v6.4.8.1 and Virtualbox manager: 4.1.4r74291) into windows\system32\VBoxNetFltNobj.dll and Portable-VirtualBox\app64\drivers\network\netflt\VBoxNetFltNobj.dll
Then the bridged networking option works in portable virtualbox - I am able to select it and I see my proper network adapters.

However when I start the virtualbox manager, I first get this error:

"
Failed to access teh USB subsystem.

Could not load the Host USB Proxy Service
(VERR_FILE_NOT_FOUND). The servie might not be installed on the host computer.

I am now able to select the bridged adapter option in networking. But:


then when I start the virtual machine I get this error:

"
Failed to open a session for the virtual machine Win7.

I also noticed, that I am able to do this only once. When I restart the portable virtualbox, the bridged adapter option is disabled again.
Portable virtualbox seems to delete the file windows\system32\VBoxNetFltNobj.dll on exit.
If I want to make the option available again, I have to re-upload my old VBoxNetFltNobj.dll in windows\system32\
