Hello, I want to intall the "Fluid Scenario Creation". To do that I first downloaded the 3DExperience Launcher and then I clicked again on the native app. No matter the choice I made between "All granted roles" and "All roles containing ..", I have at bottom left the error message : Installation Error. 
Do you have any idea why this is happening ?
