Command Center
The default settings page: launch Roblox, see what's going on, and jump to the tool you need.
The Command Center is the first item in the settings sidebar and the page Agentstrap opens on. It exists to answer three questions quickly: can I launch right now?, is everything healthy? and where do I go next?
Where it lives.
Settings → Command Center. It is the default landing page.
Launch
| Button | What it does |
|---|---|
| Launch Roblox |
Starts the Roblox Player through Agentstrap, showing the normal bootstrapper progress window. It
re-registers the roblox:// and roblox-player:// protocol handlers, records the
launch status, and may prompt for administrator rights.
|
| Launch Roblox Studio | The same, for Roblox Studio. Studio launches skip the "confirm launches" prompt. |
Media Feature Pack.
Launching Roblox needs the Windows Media Feature Pack. If
mfplat.dll is missing, the launch fails
with "Launch failed — Windows Media Feature Pack (mfplat.dll) is missing." Install
Media Feature Pack for Windows from Windows Optional Features and try again.
Status
Six read-only cards. They tell you the state of the install at a glance.
| Card | Shows |
|---|---|
| Roblox Player | Installed or Not detected, based on whether the player executable exists inside the current version folder. If it isn't installed yet, it gets installed the next time you launch. |
| Last launch | The outcome of the most recent launch — for example Roblox process started, Client startup detected, Launch cancelled, Launch failed or Launch did not complete — with the local time it happened. Defaults to No launch recorded. |
| Agentstrap | The running build version. |
| NEXUS | Off, or On (channel) when the experimental feature channel is enabled. See NEXUS mode. |
| Process priority | The priority applied to the Roblox process — Realtime, High, Above normal, Normal or Below normal. Defaults to Normal. |
| Test mode | Whether test mode is on. Test mode is toggled from the status bar of the settings window, not from this page. It makes Agentstrap relaunch Roblox after settings close, and reopen settings after Roblox closes, in a loop. |
Tools
| Button | What it does |
|---|---|
| Check for updates | Jumps to the Updates page. |
| Run diagnostics | Jumps to the Diagnostics page. |
| Open logs | Opens Agentstrap's log folder in Explorer. |
| Advanced | Jumps to the Advanced page. |
| Refresh status | Re-checks whether the Roblox Player is installed. It deliberately only refreshes that one card — the launch, version, NEXUS, priority and test mode cards don't change. |
| Repair Roblox links |
Re-registers the roblox:// and roblox-player:// protocol handlers in
HKCU\Software\Classes so they point at Agentstrap with -player "%1". Useful if
clicking a Roblox link opens the wrong thing. No administrator rights needed.
|
Some of these are shortcuts, not actions.
Check for updates, Run diagnostics and Advanced only navigate to another page — they
don't start a check. Use Refresh status if you want the install card re-evaluated without
leaving the page.
