Improve Zen Installer to remind user to download generic version if setup failed

[mr-cheffy]

What feature would you like to see?

If setup failed, we can catch this exception to remind user to download generic version instead.

What platform are you seeing the problem on?

Windows

Additional context

We could check if zen.exe failed to run using the installer, this should be possible because piping between installer and zen.exe is possible.
