# Can't start a run

> You need an active tester, an environment, cases on a cycle, and a cycle that's actually ready.

**Start a run** stays disabled or errors when the round isn't executable. Check these in order.

## Active tester

You must be an **active tester** on the project (**Assignments**). "I own the org" is not always enough if you never assigned yourself. Wizard "mostly me" usually does this; manual setup often doesn't.

## Environment

Cycle needs an environment with a real `base_url`. Create on **Environments** (**Add First Environment**). If the list page won't let you edit a typo, recreate.

## Cases

Empty cycle = nothing to run. Include `case_ids`. Cases should be `active`, not only `draft`/`deprecated`. Install a pack or **Add First Case**.

## Cycle state

A **draft** cycle may not be what you want to execute. Move toward **active**. Archived cycles are the wrong place to start.

## Still no

Wrong project in the switcher. Refresh. If the button is labeled **Launch Quick Run** and fails the same way, it's the same prerequisites.
