To start using the Virto Calendar web part on modern sites/pages of SharePoint 2019, please follow the steps below:
Create a Tenant App Catalog in your SharePoint if necessary.
To install the Virto Calendar web part, run the Setup.exe file under the farm administrator account (right-click the Setup file and choose "Run as administrator").
The .sppkg file will be automatically uploaded to your Tenant App Catalog under "Apps for SharePoint."However, please verify the existence of the .sppkg file in your app catalog. Alternatively, you can download the file directly from https://virtostorage.blob.core.windows.net/download/addin/virto-calendar-modern-webpart.sppkg.
Now you can add the Virto Calendar to modern pages/sites.
Please do not use the service administrative account to install and activate the SPFx web part on your sites.
The Virto Mini Calendar SPFx web part is also available. The installation process is the same as for the Virto Calendar SPFx web part. Simply choose "Virto Mini Calendar Modern web part" when adding it to a SharePoint site page.
