An alternative bootstrapper for Roblox with a bunch of extra features.

Bloxstrap

An open-source, alternative bootstrapper for Roblox.

This is a drop-in replacement for the standard Roblox bootstrapper, providing additional useful features and improvements. This does not touch or modify the game client itself, it's just a launcher! So don't worry, there's no risk of being banned for using this.

Running into a problem or need help with something? Check out the Wiki. If you can't find anything, or would like to suggest something, please submit an issue or report it in our Discord server.

Bloxstrap is only supported for PCs running Windows.

Installing

Download the latest release of Bloxstrap, and run it. Configure your preferences if needed, and install. That's about it!

Alternatively, you can install Bloxstrap via Winget by running this in a Command Prompt window:

> winget install bloxstrap

You will also need the .NET 6 Desktop Runtime. If you don't already have it installed, you'll be prompted to install it anyway. Be sure to install Bloxstrap after you've installed this.

It's not unlikely that Windows Smartscreen will show a popup when you run Bloxstrap for the first time. This happens because it's an unknown program, not because it's actually detected as being malicious. To dismiss it, just click on "More info" and then "Run anyway".

Once installed, Bloxstrap is added to your Start Menu, where you can access the menu and reconfigure your preferences if needed.

Features

Here's some of the features that Bloxstrap provides over the stock Roblox bootstrapper:

• Persistent file modifications, includes re-adding the old death sound!
• Painless and seamless support for Discord Rich Presence - no auth cookie needed!
• A customizable launcher look
• Lets you see what region your current server is located in
• Lets you have multiple Roblox game instances open simultaneously

All the available features are browsable through the Bloxstrap menu.

Bloxstrap also only runs whenever necessary, so it doesn't stay running in the background when you're not playing.

bloxstrap's Issues

suggestion: the old roblox ui

is the 2013 and 2016 ui possible as a client modification?

its ok if its not lol

Im having troubles with getting back to the bloxstrap setup menu

I set it up but want to go back to the screen where you customize how you want your client to be

"failed to download or apply critical settings."

Whenever i try to open bloxstrap, this error pops up, what do i do to resolve it? or do i just delete the old launcher.

i can't move in roblox, in any game whatsoever.

i don't know if this is a problem with bloxstrap, or roblox, but i've also tried plugging in another keyboard, switching the build channel, and nothing worked.

stuck on the installation window

after getting done with the preferences, the installation process for BloxStrap seems to go on forever.

Bloxstrap crashing when changing settings

Bloxstrap is crashing when i trying to change settings, (like enabling old cursor or change instalation folder)

bandicam.2022-10-31.17-25-54-098.mp4

I tried everything, (like download both x86 and x64, reinstall) and nothing helped.

Anyone can help?

"Bloxstrap is already running. Please close any open Bloxstrap window."

I have an extension called RoGold installed on my browser that lets me pin certain games on my homepage

But when I try to click the "play" button, this error pops up from Bloxstrap:

Is this the extension's fault? When I try to play games the normal way, it launches fine.

How do I redo the installation?

I installed on the version that had a broken installation menu, and now I'm unable to bring it up to change the settings even after I updated.
I tried deleting all files relating to Bloxstrap and reinstalling Roblox, but it still doesn't bring the menu up.
If there is currently no way to preview, what are all the update channels? I want to see the hidden ones I couldn't view due to the broken menu buttons.

Join link from RPC launches game with wrong account

Tried to join my friend in a game, and it launched one of my alt accounts instead of my main account. Unsure how this happened

no version of .net allows me to use bloxstrap

Installed bloxstrap and saw that i didnt had .net runtime, so i went and downloaded the latest, and it did not remove the warning, so i checked the warning and saw that it wanted 6.0.5, so i downgraded from 6.0.8 to 6.0.5 and it still did not got rid of the warning, so i reinstalled the bloxstrap installer to see if it just didnt register .net runtime. Nope, it still doesn't let me use bloxstrap

Bloxstrap suddenly stopped working

My bloxstrap client suddenly stopped working, I couldn't launch the game neither the configuration executable. I couldn't even uninstall it, so I had to use BCuninstaller to force remove it. Now I cannot even install bloxstrap - the installation file launches correctly, but once I press Install the window disappears and nothing happens.

what's this "builds channel" in the installation tab of the configure bloxstrap app

title says it all

Error on launch

When I launch Roblox with the browser, it sits at Applying Modifications for ~10sec and then it gives me this error.

Roblox Studio Support

This is just some suggestion since roblox studio is also part of roblox so y not

Same thing but with built-in
-Roblox studio mod manager
-Fps Unlocker
-RPC (show how long we have been in studio)
-etc

Roshade support

If you install bloxstrap roshade does not detect roblox since its installed in another location. Add an option to auto install roshade like the fps unlocker.

System.UnauthorizedAccessException

Usually Bloxstrap works the first time I install it, but if I change anything like including the fps unlocker, or changing build channels, this happens

Error fix?

Hello, need change client to ZCanary, I clicking edit and giving that error. What is that and I can fix that?

Was trying to do this but couldnt figure out how to get the job id

Can't launch Roblox using Bloxstrap, related to rbxfpsunlocker

Whenever I try to install Bloxstrap or play a game, I get this error (refer to uploaded image)

This could be because of rbxfpsunlocker getting an update recently.

Not really an issue but info for any exploiter.

I'm pretty sure this stops auto-inject, Doesn't work correctly with Synapse X. Just beware.

RPC unable to be launched

RPC is turned on [from the screenshot below]

Game is being played with RPC on

2010 and earlier bootstrapper style

You should add the 2010 and earlier bootstrapper style, and it should look like the image below.

Is FFlag modification ui planned?

rbxmultiple

a option to turn off the prompt stoping you from running roblox if its already open, this would be helpfull for rbxmultiple users

Add to Winget

I'm planning to add Bloxstrap to Winget, but some issues need to be resolved on the Bloxstrap side:

Issues to Resolve

• Command-line arguments so Bloxstrap can be installed and upgraded silently
• A silent uninstall switch to suppress this dialog:
  
• DisplayVersion should be properly set in the Add or Remove Programs list
  

Todo

• Add Bloxstrap to winget-pkgs (microsoft/winget-pkgs#92827)
• Add Winget Releaser workflow (#63)

suggestion: make a discord server

you should make a discord server about the plugin for ease of use and for people to get better help if you're inactive but a member knows the solution but can't comment since they don't have a github account, i mean, that's not a good reason but i still think a discord server would be useful

Bloxstrap uses an outdated version of fps unlocker

The fps unlocker was given a patch for the november 9th update but still errors when opened with bloxstrap, leading me to believe that the one integrated into bloxstrap may be an outdated version.

New 1.50 update not working for windows 32 bit

it seems like the new 1.50 bloxstrap update doesnt work for windows 32 bit and there is no option to choose which version of it you want to download

Would it at all be possible to have an option to remove the new desktop app part from Bloxstrap?

https://github.com/lolmanurfunny/Roblox-Launcher-minus-the-app has managed to do this quite well, but i've just discovered bloxstrap and would like to see either them combined or be able to have the option here for what that one does

launching bloxstrap as of november 9th launches the roblox desktop app

apparently something happened and the roblox client won't launch with the browser anymore

How do I turn off the roblox app beta

I cant find an option for it anywhere

Old in-game textures

You should include old in-game textures. There are packs online like here for example https://gamebanana.com/mods/download/7661#FileInfo_547660 or you could rip them yourself.

Bloxstrap mutes Voice chat

When you try to use voicechat with the Bloxstrap launcher it will fully mute everyone.
I had to uninstall Bloxstrap just to play with voicechat once, I will reinstall it as soon as I stop using voicechat or when its fixed.

Suggestion lists

Dunno where else to post this but I just have a couple suggestions that would be pretty cool to see in a update:

1. Custom client icon
   Pretty sure most people have suggested this before and maybe there is a reason for it not to be added so I won't go on about it for to long but basically just allow an option to change the actual client logo

2. Custom launcher icon
   Similar to custom client icon except with the launcher, the launcher uses the bloxstrap icon when loading a game in the taskbar, it would be pretty cool if we could change that, it would make it more seamless

3. Multi-clients mod
   I can see this not being added but maybe add a mod that allows us to open multiple clients

4. Choose to use desktop mode
   When closing a Roblox client it will usually prompt us are we sure and will send us to the desktop app, would be cool to have an option to toggle this, I haven't actually tested how it works on BloxStrap (I forgor 💀) but I'm pretty sure it automatically removes this pop-up so having an option for it to appear would be interesting if possible

5. Game specific mods
   So certain mods will only load in certain games, could potentially be done by making a folder in the "Modifications" folder and giving it the name of a place ID

I hope you like my ideas :)

Removing files

Is there a way for bloxstrap to delete files, instead of modifying them? Thanks.

1.4.1 detected as malware from windows defender

Bloxstrap won't start correctly due to a previous setting

Running Bloxstrap v1.5.2.
This error pops up, I believe if you have the RFU auto close option set to false. It triggers when your browser launches the Bloxstrap client while RFU is open beforehand.

Here's my settings.json file:

{
  "Channel": "LIVE",
  "VersionGuid": "version-d780cbcde4ab4f52",
  "CheckForUpdates": true,
  "BootstrapperStyle": 3,
  "BootstrapperIcon": 0,
  "Theme": 2,
  "UseDiscordRichPresence": true,
  "HideRPCButtons": true,
  "RFUEnabled": true,
  "RFUAutoclose": false,
  "UseOldDeathSound": true,
  "UseOldMouseCursor": false
}

keep saying im using build channel znext and other fluf

suggestion: make the app icon modifiable

is there a way to modify the roblox app icon/bloxstrap's icon on the taskbar when loading a game? i have a 2016 pack installed on the mods folder together with a theme on the roblox website, and the only finishing touches i need are the ability to change the app icon on the taskbar when loading a game, and when inside a game

Discord Rich Presence not working

Just fresh installed the newest version of Bloxstrap, appears that Discord reads my game as the standard Roblox client and not Bloxstrap. I have the feature enabled on the config settings for Bloxstrap and the bootstrapper is clearly running in game (I can tell because of the death sound). However, the Roblox icon on taskbar remains the same, and the Discord game activity just reads "playing a game" with the standard Roblox name and logo.

RobloxLauncherBeta cant be found

I had the RobloxLauncherBeta, but it updated to RobloxPlayerLauncher, how do i fix this?

SteamVR opens when playing any game

Only just started happening today; when trying to play any game with Bloxstrap, the SteamVR status window will open along with it

Error while launching: System.IO.DirectoryNotFoundException: Could not find a part of the path

Whenever I launch via Bloxstrap or even update Roblox with it, it gives me the error "System.IO.DirectoryNotFoundException: Could not find a part of the path". It happens after I updated Bloxstrap from 1.3.0 to 1.4.1.

How to replicate:
Update from 1.3.0 to 1.4.1 (Bloxstrap)
Before launching Bloxstrap, configure and set channel to ZAvatarTeam
Launch Bloxstrap

And now I can't launch Bloxstrap even if I set the channel to live or re-install it. (It did work on 1.3.0)

can you please make a version of this app that DOESNT require you to install .NET x86?

Alternate way of accessing the settings

Currently the only way of accessing the settings is in the readme: open up Apps and Features, look for Bloxstrap and select Modify. The problem is that some users (such as myself) can't locate "Bloxstrap" in "Apps and Features". And no, the "Apps" section in the modern Settings app can't locate it either.

Normally, Bloxstrap should be somewhere in the list, but it isn't.

Perhaps a command-line parameter such as --settings could be done?

Add an updater to the bloxstrap launcher

Instead of directing users to the newest release's page, it could just upgrade the bloxstrap version

"An error occurred while starting Roblox" error when trying to install Bloxstrap

So I've been trying to install Bloxstrap and I keep running into the same "An error occurred while starting Roblox" error
Roblox works fine outside of this but whenever I try to install Bloxstrap it just gives me an error

Error:

Configure file is not installing along with Bloxstrap

I started having this problem a few weeks ago, whenever bloxstap would update the configure file wouldn't be installed with it, also seems to have deleted itself since I cant find it by name on my computer anymore.

Unchecking "Allow people to join" option should only hide the `Join` button

Windows Defender flagging something in Bloxstrap
