I have tried to install ARRv3.0 on a windows 10 machine and resulted in the downloaded file failed due to a signature verification check. We have automated the deployments which attempt to install ARRv3_0. Manually installing the ARR doesn't help in my situation. There is a previous post related to the same issue which is resolved. The latest updates on ARR again opened it.
