When I head to AutoDesk website and download Revit with parallel desktop on MacOS Big Sur 11.5.2, the web navigate me to a site Bad Request 400. In the past, I have not experienced similar problem. However, on a PC, Revit could be downloaded and does not lead to a bad request 400. Therefore I doubt the problem is raised due to the virtual desktop nature. parallel desktop information: Version: Parallel Desktop 17.0.0 (51461) Pro Version Mac Information: MacOS Big Sur 11.5.2 GPU: Radeon Pro 560X 4 GB Memory : 32 GB 2667 MHz DDR4
