When opening up a Revit model you all of the sudden get a pop up message stating that your file was modified by a third-party updater called AREXRevitStart : REXExtension: DReinfWall.
This message is popping up because someone working on the model has the Reinforcement extensions from subscription center installed and the user getting the message doesn't.
Solution:
- Open the model with Audit checked. With this option I have had users complain that the message still pops up.
- You can move forward by selecting "Do not warn and continue working with the file" but users have complained that it will pop backup upon reopening the file.
- Your last option that for me always works is to just install the Reinforcement extension from your Autodesk Account or from the Autodesk Desktop app.
- For 2019 and 2018 it will be the Structural Precast Extension, there is an update for this as well.
- For 2017 and 2016 it will be the Revit Extensions.
