The Rob Run loader will not start. What should I check first?

Start with the setup guide order: rename the loader, right-click it and run it as administrator, then paste your key. Running it without admin rights is the most common cause.

I did run it as admin. It just closes.

Then it is almost always security software. Check the pre-setup in your guide: antivirus off, Windows Defender off, and Core Isolation and the driver blocklist off. Also check the status page, and only download the loader from the mega.nz link in your setup guide, never from a file someone sends you.

If it still closes, note the time and what you did right before, and open a Discord ticket with your order number and Windows version. That gives support something to work with.

And if you only get the menu and no ESP after the loader works, that is a different problem: you probably injected in the lobby. Inject again from the game world.
