Installing Virto Notifications & Alerts On-Premises
Before you begin, you need to make sure you have access to the server and your account must have the appropriate administrative privileges to install applications.
Download the package for your SharePoint version (for example Virto.SharePoint.SE.AlertsCustomizerWebPart.zip) and unzip it. It contains two folders:
- Virto.SharePoint.Alerts.Setup — the setup program (SetupSE.exe for SharePoint Server Subscription Edition, Setup.exe for the other versions), Deploy.ps1, the solution Virto.SharePoint.AlertWebPart.wsp and the modern web part package virto-alerts-reminders.sppkg;
- Virto.WebLicenseManager — Virto License Manager, installed or updated together with the product. See Installing and updating the License Manager.
Run the setup program as a farm administrator and follow the wizard: system check, license agreement, web applications, installation.
Note: the screenshots below show the setup wizard for SharePoint 2013; the installation procedure is similar for the other SharePoint versions.

The wizard performs a system check prior to the installation. All the system checks must be completed successfully in order to proceed with the installation. After the checks have completed, click “Next”.

Check “I accept the terms in the License Agreement” and click “Next”.

Select the web application(s) where you want to install the product.
Warning: You must be logged in to the SharePoint server with a Site Collection Administrator account to automatically activate this feature.

Then click “Next”.

Click “Close” to complete the installation.

Installing with Deploy.ps1
Instead of the setup program you can run Deploy.ps1 in the SharePoint Management Shell as a farm administrator; if the solution is already installed, the script updates it.
