Hi there,
We have finished moving the MCDU Remote Display feature to SimBridge for our Development version. SimBridge is now required if you would like to continue using this feature and future remote displays.
Please see the following documentation:

Stay up-to-date with SimBridge:

NOTE: Stable version still uses the non-SimBridge version utilizing the server.exe
