Network Driver Installation Issues - SOLVED

[bryanc]

For some months I have not been able to successfully install bridged networking on Vista SP 2. I now have a solution to the problem.

1. Uninstall VirtualBox

2. Delete the directory C:\Program Files\Oracle\VirtualBox
I am not sure why the uninstall didnt do this (VirtualBox 3.2.12r68302)

3. Reboot Windows

4. Run regedit.exe (as administrator)

5. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network

6. Delete the key Config

7. Exit regedit and reboot Windows

8. Install VirtualBox

9. Reboot Windows

10. Run VirtualBox

This process worked for me. It may not work if you dont have the same symptoms that I had.

I found this solution in a forum at http://serverfault.com/questions/1421/s ... ork-driver

Hey Bryan,

Your post helped me find where to look; however, deleting the config key did not work (at least it didn't in my Win7Pro x64 host). Although, what did work is in the same area, there is a key called MaxNumFilters. On my end, that was set to 8. I changed that value to 20 (which is 14 hex). Reboot and bingo. Problem solved... bridged adapter now installed properly when running vb installer.

THANKS!!!

The trick with MaxNumFilters helped me install 4.3.12-93733
Took me hell of a time (and lots of install combination and googling) to figure out that it was "Bridged networking support" which gave the problem.
