Hello,

The Vuforia Engine SDK is now integrated with the Unity Editor starting with 2017.2. You can select it when installing the Unity package.

Thanks,

Vuforia Engine Support

how can i get the download link ?

how can i get the download link ?

Meanwhile we have replaced the ZIP with the actual unitypackage; you can re-download it.

I think this should be the right solution... I will try it and post back.
Thanks

If you are using Mac,

That's because the unity-package file (inside the ZIP) is also a compressed archive; 

it's a bit like having a Zip which contains another ZIP; if you double-click the ZIP file on Mac, the extractor will identify the  unitypackage file (inside the ZIP) as another archive, and will directty dig down inside the unitypackage and will extract the content of the unity-package.

However you can extract the ZIP file without double-click and you should be able to get the actual unitypackage file.
