How to Switch Between Roblox and Bloxstrap?
Switching between the normal Roblox launcher and Bloxstrap sounds confusing at first, especially when each guide online explains it differently. Some sites make it sound complicated, some leave out important steps, and some assume you already understand how launch handlers work. This guide is written for everyone beginners, casual players, and people who just want Roblox to open the way they prefer.
By the end of this article, you will understand exactly how switching works, why it works that way, how to switch instantly, how to fix issues, and how to manage Bloxstrap or Roblox as your default launcher at any moment. Everything is written in simple words, without technical phrases, so you can follow it easily.
Difference Between Roblox and Bloxstrap
Before learning how to switch between them, it helps to know what they are. The standard Roblox launcher is the basic program that opens when you click Play on the Roblox website. It updates your game and opens a client. You cannot customize much with it.
Bloxstrap is a replacement launcher. It takes over the job of launching Roblox but adds extra features like modding support, FPS unlocking, theme changes, startup settings, and multi instance launching. When Bloxstrap is registered as your launcher, clicking Play on the website will open Roblox through Bloxstrap instead of the official launcher.
Switching between the two is basically telling Windows: “Use this launcher instead.”
Everything you do revolves around that one simple system.
How Switching Works Behind the Scenes
When you click Play on Roblox.com, your browser does not open the game directly. It hands the job to a program on your computer that knows how to launch Roblox. That program is called the bootstrapper. Roblox has a default bootstrapper, and Bloxstrap has its own. You can register either one, which decides who launches the game.
That’s all switching really is:
Choosing which bootstrapper Windows should use.
There’s no reinstalling Roblox, no deleting files, no complicated editing. You launch the one you want, and it sets itself as the default.
How to Switch From Roblox to Bloxstrap
This is the easiest switch. In fact, Bloxstrap is designed to take over automatically when you open Roblox through it once. Follow these steps and you’ll be using Bloxstrap as your launcher.
Step 1: Install Bloxstrap From the Official Source
Make sure you install Bloxstrap only from:
- bloxstrapps.com (official site)
- github.com/bloxstraplabs/bloxstrap (official GitHub)
Avoid every other site, especially ones with ads or random downloads. Fake Bloxstrap copies exist and can contain malware.
Download the latest version, run the installer, and complete the setup. If Roblox needs .NET Runtime, Bloxstrap will guide you through installing it.
Step 2: Launch Roblox Using Bloxstrap Once
After installation, open Bloxstrap and click Launch Roblox or simply join a Roblox game through the website. The moment Bloxstrap successfully launches Roblox:
Bloxstrap becomes the default launcher automatically. You don’t need to click any extra buttons or change Windows settings. Bloxstrap registers itself when you use it for the first time.
From now on:
- Clicking Play on Roblox’s website opens Bloxstrap
- Desktop shortcuts also point to Bloxstrap
This is how Roblox players switch to Bloxstrap.
Step 3: Customize Bloxstrap Settings (Optional)
After switching, you can open Bloxstrap again and set up features like:
- FPS unlocker
- Multi-instance support
- Themes
- Modding (fonts, sounds, textures)
- Discord Rich Presence
- Fast Flags
- Startup settings
None of this is required, but Bloxstrap offers much more control than the official launcher.
How to Switch Back to the Official Roblox Launcher
Sometimes you want to turn off Bloxstrap or use the normal Roblox launcher again. Maybe a mod is broken, maybe Roblox changed something, maybe you just like the official launcher better. Switching back is as simple as switching to Bloxstrap, but the steps are different.
Step 1: Find the RobloxPlayerLauncher.exe File
The official launcher does not show up in the Start Menu. You must open it from its folder.
It’s almost always located here:
*C:\Users\YOURNAME\AppData\Local\Roblox*
Inside this folder, find:
RobloxPlayerLauncher.exe
This is the official Roblox launcher.
Step 2: Run the Roblox Launcher Once
Double-click RobloxPlayerLauncher.exe.
Running it tells Windows:
👉 “Use the official Roblox launcher again.”
Now when you click Play on Roblox.com, the game will launch with the original bootstrapper instead of Bloxstrap.
This single step switches everything back to normal.
Step 3: Test the Switch
Join a Roblox game from the website. If the Roblox Player loads without the Bloxstrap window, then the switch worked perfectly.
If Bloxstrap still opens, don’t worry — the next section explains how to force the switch.
If Roblox Still Opens Through Bloxstrap (How to Fix It)
Sometimes Windows does not update the launch handler immediately. If the official launcher didn’t register correctly, here’s how to force it.
Fix 1: Re-run the Official Launcher
Open RobloxPlayerLauncher.exe again.
Sometimes it takes two launches to overwrite Bloxstrap.
Fix 2: Open File Location Through a Roblox Shortcut
If you have a Roblox shortcut:
- Right-click it
- Select Open File Location
- Run RobloxPlayerLauncher.exe from that folder
This ensures you’re launching the correct file.
Fix 3: Reinstall Roblox
If nothing works:
- Uninstall Roblox
- Delete the entire Roblox folder in AppData
- Reinstall Roblox from Roblox.com
- Launch a game once
This resets all launch settings to default.
