Windows – Genymotion error at start ‘Unable to load virtualbox’

genymotionvirtualboxwindows

I've installed the genymotion+virtualbox package on Windows 7 64-bit and everything goes fine… But when I start Genymotion it presents me an error message Unable to load virtualbox.

VirtualBox is installed and I'm able to start it manually. I've tried to install the packages separately, updated virtualbox to 4.2.16 but nothing worked.

I've already read genymotion FAQ but it did not help.

I have spend all day to solve this error since none of the answers worked for me.

I found out that oracle virtual box doesn't install the network adapter correctly in windows 8.1

Solution:

  1. Delete all previous virtual box adapters
  2. Go to device manager and click "Action" > "Add legacy hardware"
  3. Install the oracle virtual box adapters manually (my path was C:\Program Files\Oracle\VirtualBox\drivers\network\netadp\VBoxNetAdp.inf)

Now that virtual box adapters is installed correctly, it needs to be setup correctly. (the following solution is like many other solution in here)

  1. Start Oracle VM VirtualBox and go to "File" > "Preferences" > "Network" > "Host-only Network"
  2. Click edit
  3. Set IPv4 192.168.56.1 mask 255.255.255.0
  4. Click DHCP Server tab and set server adr: 192.168.56.100 server Mask: 255.255.255.0 low address bound: 192.168.56.101 upper adress bound 192.168.56.254
  5. Now click OK and start genymotion
