Hi,
FSX requires Simlink plugins to connect with the Simlink application.
Please check the Simlink application to see if the plugins for FSX are installed. If FSX is not listed as shown in the image below, please install the plugins using the Simlink Plugins Window.
After installing the plugins, launch FSX. During startup, you will receive a message prompting you to enable the Simlink plugins. Please make sure to allow the Simlink plugin in FSX.
If you continue to experience issues, feel free to reach out to us.
Thank you.
Best Regards,
Vishal Ahir
