If you already use Virto SharePoint Related Items and need to upgrade it to the latest version, download the.zip file from http://www.virtosoftware.com. Unzip the file and run setup.exe.
On the step 3 check the box “Upgrade” and click “Next”.
Note: if you had activated the license while installing the previous Virto SharePoint Related Items version, you do not need to activate it now.
