# Roblox won't launch

Believe it or not, this usually isn't related to Horizon itself, but rather a design flaw of Horizon. **Do NOT make tickets for this as it is unrelated to Horizon**.

First, press the windows key and type 'Disk Cleanup'. Launch the application - it should look like this (after it initializes):

Un-Check **everything** and then check '**Thumbnails**', press 'OK', and then press 'Delete Files'. Again, if this does not work try to follow the section titled '[Bans](https://horizon-7.gitbook.io/horizon/hardware-related-issues-and-bans/bans)', as you may be Silent HWID banned.
