Xamarin - Cant start SDK or AVD

So I have just installed the community version of Visual Studio 2017 and added Xamarin to it. When the installation was over, a error log was created saying in it that the SDK and Emulator components were not downloaded properly. So I redownloaded and same thing. I then tried modifying and repairing, again nothing helped - still the same problem.

Now when I start VS without minding the errors, I am not able to access the SDK and AVD. I click on the icons and nothing happens. I checked the path to the SDK (looks alright to me, but I guess as the error log said - SDK might not be properly installed).

I am in a corporate environment and am not allowed to download just the SDK from the android website.

I am basically trying to reach out to you all for help. All tips and answers are appreciated.

Cheers!

IF you are using windows 10, check if Hyper-V and Hyper-V Tools are installed. Open the RUN Command on your start menu, or using Windows + R - Type "appwiz.cpl" - click on "Turn Windows features on or off" and check if Hyper-V are selected and installed.

If not, select-it and restart your machine, and this mus solve your xamarin issue.

If, this dont solve, this could be a firewall issue, and this maybe blocking the download of xamarin tools.
