Message 'Requested registry access is not allowed' when a Controller error occurs for the first time on a restricted client device (for example Citrix server)

Troubleshooting

Problem

When using Controller, the user generates a problem. By design, Controller logs its error messages inside the Windows Event Viewer (Application Log). For this process to work, it needs to create a registry key. However, the first time that it does this, if the end user is not an administrator it cannot create the registry key. The end user therefore sees a different (non-specific) error message.
