Genymotion error after windows 10 upgrade

Solution 1:

I solved this issue. It's working fine now.

I'm using:

+ Window 10
+ VirtualBox-5.0.2-102096-Win
+ Genymotion-2.5.3

Step 1: We should set Run as this program as an administrator & Compatibility mode Window 7 for those file.

C:\Program Files\Oracle\VirtualBox
    + VBoxHeadless.exe
    + VBoxManage.exe
    + VirtualBox.exe
C:\Program Files\Genymobile\Genymotion
    + genymotion.exe

Step 2: My Computer -> Manage-> Device Manager-> Network adapters

Remove all items with name: VirtualBox Host-Only Ethenet Adapter #...

Step 3: Open Virtual Box and go to File -> Preferences -> Network -> Host Only Networks

Remove all and create new host with information:

Adapter Tab:
    IPv4 Address:        192.168.1.201
    IPv4 Network Mask:   255.255.255.0
DHCP Server Tab:
    Server Address:      192.168.1.100
    Server Mask:         255.255.255.0
    Lower Address Bound: 192.168.1.101
    Upper Address Bound: 192.168.1.199

Step 4: Run Genymotion again. It's will work.

Solution 2:

I used to have the same issue. I've download VirtualBox 5 an reinstall it (or repair) over the old install. Reboot and that's it.
