# Error: Failed to launch application

Problem: When trying to run a Cloudhouse Application Compatibility Package (also known as a *Cloudhouse Compatibility Container*), the following error is displayed, "Failed to launch application. Please contact support."

Applies to: `Alchemy`

**Cause**: This error is displayed if your License has expired.

**Solution**: To fix this issue, ensure the License within the ACP you are trying to run has not expired by completing the following steps:

1. Open the `RunWorkflowLog.txt` (located in the root of the deployed ACP) in a text editor.
2. Check for the existence of the following line:

- `Cloudhouse.Container.Core.Exceptions.InvalidLicenceException: The provided licence has expired`.

!!! tip

    If your License has expired, ask your Cloudhouse Partner/Cloudhouse Support to regenerate you a new Auto Packager License. Then replace the expired License with the new one which will allow you to run the Auto Packager.
