Windows 8.1 Pro x64 - virtualbox 5.0 don't install

[marcussoares]

Hello guys,
I'm need very much help for installing the new version of VirtualBox 5.0
Before I had installed VirtualBox 4.3 on my machine and also Microsoft Hyper V (Windows 8.1 Professional x64).
But I downloaded the new version (virtualbox 5.0) and have been trying to install the same and have only gotten errors.
Already realized uninstalling the 4.3 version of virtualbox and also uninstalled Hyper V, already accomplished registry cleaner using Revo Uninstaller Pro but still can not install.

Below I leave an image of the installation error:

Try running the installer using "Run as administrator".

Hi mpack,
I've tried to install as an administrator, but did not get success.

The only other feature to look at, that I know of, is the MaxNumFilters registry entry on the host. The control the maximum number of servers that can attach to a network card. The default is 8, but you may need to increase it.

The web page below explains the issue in a similar context :-
