RBXTester
Set up RBXTester
RBXTester runs your Roblox tests on a Windows machine of its own. This installer sets that up end to end — it installs VMware Workstation, downloads the test machine, installs it, boots it, and connects it. You press one button, answer Windows once, and wait.
Windows will warn you before it runs
RBXTester is not code-signed. When you run the installer, Windows shows a blue “Windows protected your PC” box and hides the Run button behind a link. Click More info, then Run anyway.
That warning is about a missing signature, not about anything the
file does. If you would rather check the file than take its word for
it, the installer’s SHA-256 is below — compare it against
Get-FileHash RBXTester-Setup.exe.
Check the download yourself
Run the command below in the folder you saved the installer to. The two hashes must match exactly.
Get-FileHash RBXTester-Setup.exe -Algorithm SHA256
What it installs
- VMware Workstation A free-for-personal-use hypervisor, mirrored here so no vendor account is needed.
- The test machine A Windows image with Roblox Studio already installed, signed out of every account.
- About an hour, nearly all of it downloading The machine is about 31 GB. The download resumes if you close the app or restart the computer.
- Two moments Windows needs you Installing VMware needs administrator rights, so Windows will ask you to allow it. Later it has to restart once to finish installing VMware's network adapters — RBXTester reopens itself afterwards and carries on from where it stopped. Everything else runs on its own, so stay near the machine until both have happened.
What you will need
- Room for the machine About 63 GB free on the drive you choose: the 31 GB image downloads there and the disk it unpacks to lives there too. You pick the folder during setup. RBXTester measures the drive before it downloads a byte and tells you what it found if there is not enough room.
- A machine that can run VMware Hardware virtualisation has to be turned on in the BIOS. It is by default on nearly everything built in the last decade; it is the setting to check if VMware refuses to start a machine.
- Three things only you can do At the end, RBXTester asks for your model provider’s API key, the place id you want tested, and your Roblox sign-in. An installer is not allowed to do any of those for you, so they are a short wizard rather than part of the setup.
