A manual fix requires the following steps:

1. Create `D:\Websites_AppMetricsData\settings.xml`` with the following content

    <?xml version="1.0" encoding="utf-8"?>
    <AppSettings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <RequireAccessKey>true</RequireAccessKey>
    <AccessKeys>
        <string>{501-your-key}</string>
     </AccessKeys>
   </AppSettings>

2. Ensure metrics website has correct acls for new file - icacls d:\websites /grant "IIS AppPool\metrics.{your_tld}":F /T /inheritance:e
3. Restart metrics website - %windir%\system32\inetsrv\appcmd recycle apppool "metrics.{your_tld}"

Have updated AppMetrics installation instructions - Configure Access Keys to get around this issue manually.

When it is fixed the instructions need to be fixed too.

Fixed. Manual workaround is not necessary
