There are a few ways you can verify the version of the SDK that is installed on your machine. You can nagivate to your Control Panel and open Programs and Files feature and verify the version if Telerik Sitefinity SDK. I am attaching a screenshot to further illustrate that.
What we can do to improve your experience is to include the version in the name of the Shortcut file that is automatically created on your desktop.
All the best,
