Installing Virto Forms App for Microsoft 365

1. Add the Virto Forms Designer from Microsoft Sharepoint Store.
2. The app will appear in the Admin Center at https://[your domain].sharepoint.com/sites/appcatalog and on the ribbon.

3. When you click the app icon, the following dialog window will appear:

4. Publishing or changing a form needs custom script on the site. A SharePoint Administrator allows it with Set-SPOSite <site URL> -DenyAddAndCustomizePages 0 (Allow or prevent custom script). Microsoft switches custom script off again within 24 hours, so allow it again whenever you publish or change forms. Published forms keep working after it is switched off.

5. The first time someone opens the app, Microsoft asks for consent to Virto Forms Designer, the app’s own Microsoft Entra app (publisher VirtoSoftware UAB). It asks for Sites.FullControl.All, which only an administrator who can grant tenant-wide consent approves for the whole organization: a Global, Cloud Application or Application Administrator. Until then, people see Need admin approval. All permissions are delegated: the app acts as the signed-in person.

   Note: since October 26, 2026, Virto Forms Designer App signs in through its own Entra app instead of the shared Virto Apps. If you used the app before, an administrator consents once more. The old Virto Apps entry stays in Enterprise applications; if you don’t use Virto Calendar App or Virto Kanban Board App, an administrator can delete it.

6. Now you are ready to create custom forms in SharePoint, or by visiting https://forms-app.virtosoftware.com.
