The environment variable '{0}' cannot be set because another test run has already set this variable to a different value. The following diagnostic data adapters require this environment variable to be set:
{1}

These diagnostic data adapters might not function correctly if this environment variable has an incorrect value. You might want to stop the other test runs, or wait until they have completed, and then run these tests again so that the diagnostic data adapters function correctly.
