| This Litmus Edge instance was previously activated to a different Litmus Edge Manager. You are trying to launch an application from a catalog that has the same name as a catalog from the previous LEM. | On the Litmus Edge instance, delete any catalogs that were synchronized from other Litmus Edge Managers. Then, try launching the application again. |
