Dlunhappy226/MultiRoblox ? reverse-engineered prompt

Build me a small Windows app called MultiRoblox that lets Roblox open in more than one instance at the same time.

It should be simple for a normal user to run, and it should have a tiny setup flow so they can install it and let it run in the background when Windows starts. If Roblox is already open, the app should still be able to make the multi instance behavior work, or tell the user to restart if that’s required. I’d like it to feel lightweight, with a straightforward installer script and an easy uninstall by removing it from startup.

Use the current .NET Windows desktop approach if that fits best, and make sure it works on Windows 10 or 11. If you need to check current Roblox related details, look up the latest docs or community info online before wiring it up.
