# Selecting the Correct App per License
When installing an app from the [**Atlassian Marketplace**](https://marketplace.atlassian.com/vendors/1218845/getint-integrations-jira-azure-devops-servicenow-salesforce-asana-monday-clickup-gitlab-and-others), you may encounter issues if the installation is not performed using the correct app, especially when initiating the appropriate trial or license. Following the steps below will ensure a smooth installation and help avoid common errors such as licensing mismatches or failed installations.

If the correct app is not installed, you will encounter an **Invalid Jira license** error, which prevents any work items from being synchronized.

On the left, you can see that different apps are available depending on the connectors you want to integrate
### Troubleshooting the Invalid Jira License Error
After you create an integration, if the runs begin to fail, you'll see this message in the run logs. During this period, the integration will not sync any work items.
A warning icon will also appear beneath the license column to indicate an issue with your license.
{% hint style="info" %}
We’re using the Jira Airtable app as an example to build a ServiceNow integration and intentionally force a failure, but this message will appear in any app if you’re using the wrong connector or if your license has expired.
{% endhint %}
To resolve this issue, first assess what integration you would like to build:
1. If you are integrating with **Jira**, first verify if you have an active trial for your integration:
* **Jira Cloud**: Go to the **Subscriptions** section in your billing console and check if your subscription is active.
* **Jira DC**: Go to the **Manage apps** section and locate the Getint app. Click on it to view more information, where all app details will be available.
2. If your trial is active, go to the **Apps** section and select the appropriate app for your integration.
3. If you don’t have an active trial, go to the Atlassian Marketplace and search for **Getint**. All our apps will be listed there. Select the app you need for your integration (in this example, we’ll use ServiceNow).
4. Activate the trial if you still don’t have it:
5. Go back to your **Apps**, and launch the Getint app.
6. You should now be able to build your integrations as needed.
{% hint style="warning" %}
Note: If you are using our app to integrate (e.g., Jira-ServiceNow) and would now like to scale to integrate ServiceNow with DevOps, we can generate a new license key that will enable this within the Jira app.
This additional license key must be purchased separately. For more information, please contact our [Support Center](https://getint.io/help-center).
