Hi,
Thanks for your post.
Could please tell me what's the version of your Visual Studio?
As far as I know. After restarting your machine. It means your Visual Studio has been installed successfully. There is no need to open the installation interface again. You can open the Visual Studio directly.
You can search out the Visual Studio in Start menu then open it successfully.
If I misunderstood your issue. Please feel free to let me know.
Best Regards,
Lake Xiao
