virtualbox.org

Hello,

I installed guest additions on my Win10 VM, installation was OK, but nothing happened. I rebooted VM after installation and it haven't launched, so I wasn't able to use features as fullscreen. I looked up folder in Program files but I can't find any way to launch it. I'm using Virtualbox 5.1.6 and the same version of guest additions

Thanks for help

In order to better understand the problem you need to submit some more information. Please read the following: Minimum information needed for assistance.

Use of Windows Compatibility settings (or use /force) will not work: installer will run, but with no real effects.

Install VirtualBox 4.3.18 or newer. It has improved compatibility with Windows 10.

Note: Menu Help > Check for updates may not reflect the newest as being the latest. Download it manually instead.

@Elizine
The OP already said that they're running the latest as of this writing, 5.1.6. As for 4.3.18, that's way too old to play nice with Win10. The latest, the better.

I installed 5.1.6 today and had no problems installing the GAs on my Windows 10 guests, so it is not a general problem.
