Hi,
According to your description, my understanding is that RSAT on Windows 10 will prompts error when adding server to the console.
In general, there should be only one RAST version installed on your device. Make sure that the previous RAST has been removed:
1.
Control Panel – Programs - Uninstall a program - View installed updates.
2.
Right-click Update for Microsoft Windows (KB2693643), and then click Uninstall.
3.
Click Yes to uninstall the update.
Then restart the computer and try to install RAST for Windows 10, and confirm the result.
Click below link to download Remote Server Administration Tools for Windows 10:
