Genymotion error at start ‘Unable to load virtualbox’

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
