Virtualbox – How to Install version 4.3.26

Getting Virtualbox installed on a Windows 7 x64 was not that easy ?

Especially this version 4.3.26


I saw similar issues relating to earlier versions as well on the net.

Here are the fixes :

1st issue was running the installer that ended up in an error, and next did a ‘complete rollback’ in the installed files Sad smile

To fix it follow these steps:

Uninstall Virtualbox

  1. Uninstall Any Virtual Box Network Adaptors from Device Manager


  1. Go into the registry at: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Network
  2. Change “MaxFilters” from 8 to 20 (decimal)”
  3. image
  4. Reboot your PC (I don’t think this is needed but can’t hurt)
  5. Install VirtualBox 4.3.X (Run as Administrator)

After this change the installation ran just fine.

2nd issue

Once installed I got an other error when launching the VM.



First run this command : sc.exe query vboxdrv

If you see that it can’t find the vboxdrv driver, you need to check this registry key :


Check the ImagePath key, and make sure it holds this value

\??\C:\Program Files\Oracle\VirtualBox\drivers\vboxdrv\VBoxDrv.sys


If not change it and run this command as Administrator :

sc start vboxdrv


Once the service is RUNNING all is working fine Smile
