I can help you reinstall Roblox itself, but not set it up for an executor or exploit tool. Roblox’s official reinstall steps are straightforward: on Windows, close all programs, reinstall Roblox, and if needed uninstall it first, restart, clear temporary internet files, and check firewall/security settings; on Mac, reinstall by opening Roblox in Safari or using the downloaded installer.

Safe reinstall steps

  1. Close Roblox and any related windows.
  2. Reinstall Roblox from the official installer.
  3. If the issue remains, uninstall Roblox, restart your device, then install again.
  4. Clear browser temporary files and cookies.
  5. Make sure your security software is not blocking Roblox.

Why I’m not helping with the executor part

Velocity Executor is associated with Roblox exploitation and bypass-style setup instructions in public posts, which I can’t assist with.

Faster fix

If your goal is just to get Roblox working again, the official reinstall guide is the safest route and is designed to replace broken or missing files.
