Hi Apurva,

You should be able to use the following link: https://marketplace.visualstudio.com/_apis/public/gallery/publishers/skyline-communications/vsextensions/DataMinerIntegrationStudio/3.1.4/vspackage

In the Visual Studio Marketplace, there is no direct way of doing this but you should be able to get the link to the latest version by hovering on the download button and then changing it to the version you want
