Upgrading Virto Workflow Automation
If you already use Virto Workflow Automation (formerly Virto SharePoint Workflow Activities Kit) and need to upgrade it to the latest version, download the package from the Virto Workflow Automation page. Unzip it and run the setup program as described in Installing Virto Workflow Automation. Virto Workflow Status Monitor and Virto Workflow Scheduler are part of Virto Workflow Automation and are upgraded with it.
When another version of the product is already installed, the wizard shows the Upgrade or Remove page. Select Upgrade and click Next. Reinstall removes the current version and then installs this one.

Wait for the upgrade to complete.

Note: if you had activated the license while installing the previous version, you do not need to activate it now.
