So what should I do now?

Closes (freezes)? Or fails? In my case (bad luck) it turned out to be a problem with powershell itself. The log generated by the studio installer when adding the JIT debugger looks like this:

The product failed to install the listed workloads and components due to one or more package failures.

If you run a dos prompt (as admin), run the command listed in the Command Run section and you will see this error:



Internal Windows PowerShell error. Boot Managed Windows PowerShell with Error 80070002

You can work around this by opening a file explorer for "C: \ Windows \ SysWOW64 \ WindowsPowerShell \ v1.0" and renaming powershell.exe.config. Re-executing the powershell command from the dos prompt should run without error.
