VirtualBox no longer supports 32bit since 6.0 and the Genymotion with VirtualBox installation package includes VirtualBox 6.0.4.
Uninstall VirtualBox 6.0.4, download and install VirtualBox 5.2.32 from here.
VirtualBox recommended version is 6.0.4, so using 5.2.XX may cause bugs. It is recommended to use Genymotion in a 64bit Windows environment with VirtualBox 6.0.4 instead.
