# Known Issue: Missing Calendar Component Store App blocks Serenity - Core installs and upgrades

> [!TIP]
> ## Status
> 
> **Resolved** — See [Solution](/serenity/docs/known-issue-sn-calendar-component#solution) details below.

## Summary

Customer platform admins are unable to install or upgrade to Serenity - Core version 7.8 or newer without first opting in to the terms & conditions for the ServiceNow Store [Calendar Component](https://store.servicenow.com/store/app/3bfaabe61b246a50a85b16db234bcb5d) application.

## Description

In Serenity - Core version 7.8, a dependency was added for the ServiceNow Store [Calendar Component](https://store.servicenow.com/store/app/3bfaabe61b246a50a85b16db234bcb5d) application (*minimum* version 24.1.6).

The Calendar Component app requires a customer platform admin with ServiceNow Store access to accept the terms and conditions in order to allow it to be installed or updated. If the customer has not opted-in, the dependency will be shown as a red circle with a slash through it (see [solution](/serenity/docs/known-issue-missing-calendar-component-store-app-blocks-serenity-upgrades#solution) details below.). A previous version of the Calendar Component app may already be installed, but the customer may still have to go through the opt-in process to upgrade to the latest version.

> [!WARNING]
> **NOTE: Opting in must be performed by a customer platform admin** with access to the [ServiceNow Store](https://store.servicenow.com/store), Serenity does not have access to and can’t legally accept the terms and conditions documents on the customer’s behalf.

#### Application Manager App Listing Dependencies

On each App Listing there is a section for Dependencies.

## Scope of Impact

- The [Calendar Component](https://store.servicenow.com/store/app/3bfaabe61b246a50a85b16db234bcb5d) app must be previously installed with a *minimum* version 24.1.6 from the ServiceNow Store in order to successfully install Serenity - Core version 7.8 or newer.
- Without this store app installed, Serenity app upgrades are blocked and only a customer platform admin with access to the ServiceNow Store will be able to resolve.

## Solution

1. As a customer platform admin with access to the ServiceNow Store, navigate to the Calendar Component app listing. [https://store.servicenow.com/store/app/3bfaabe61b246a50a85b16db234bcb5d](https://store.servicenow.com/store/app/3bfaabe61b246a50a85b16db234bcb5d)
2. Click the Get button.

1. Review and accept the attached terms and conditions document.

1. Validate that the app listing shows as “Ready to Install”

> [!WARNING]
> **NOTE: After acceptance, the ServiceNow Store must sync with the customer instance** in order to enable installation of Calendar Component store app. You can force a sync from the Application Manager home, but this is not always immediately successful. Generally, the conflict clears within 30 minutes, but it could take longer.
