While installing Aras 12 I'm getting below error
If I clicked on Ok aras installing but I'm not able to do login.
No problem! If you click ok and then try to start innovator does it bring you to a blank screen with an error stating the OAuth server config file is missing? Another thing you can check is if your system Path variable also points to powershell.
You can find it in the control panel -> system -> Advanced System Settings or by hitting the windows key and searching "edit the system environment variables." Then within the advanced tab click environment variables and add the file path to the system PATH variable.
