Toolbox built-in plugin broken

I’m getting this long error every time I open a studio instance or start a test in studio:

The toolbox widget won’t show up when I click on it:


What version of Roblox Studio are you running? (Check in File → About)

This is the error that would be expected if you’re still on version 440. Upgrading to 441 should fix it.


That seemed to work. I just wish there were a better way to upgrade to the newest version of studio when restarting doesn’t work. It’s annoying to have to go through AppData and guess at which files I need to delete in order to re-install and get the latest version (hoping I don’t delete the files that I do need)

This is probably an issue arising from the fact that you’re running a Bookmarked RobloxStudioBeta.exe, rather than running RobloxStudioBetaLauncher.exe. If you run the latter, it should always successfully update and launch the most recent version when launching studio.

I always run whatever app gets added to the Start Menu, pin that to the taskbar, and then delete the desktop shortcut

Usually I get regular studio updates, but sometimes I miss minor updates; would doing this not give me the launcher?

Can you provide the following information?

  • The following values from regedit:
    • “version” in Computer\HKEY_CURRENT_USER\Software\ROBLOX Corporation\Environments\roblox-studio
    • “version” in Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\ROBLOX Corporation\Environments\roblox-studio
  • A screenshot of the contents of %localappdata%\Roblox\Versions
  • A screenshot of the contents of C:\Program Files (x86)\Roblox\Versions
  • Right click on Roblox Studio in the start menu > open file location, open file location again on the shortcut, and provide the file path
  • Open studio through the start menu, find it in the task manager (Ctrl+Shift+Esc) details tab, right click > open file location, and provide the file path

And is this failing to update when all existing instances of Studio are closed, or are one or more still open? The task manager may reveal there is a hidden instance opened.
