TZ

Set up TZ for FiveM: redeem your key on TZ Project, inject the internal cheat, and fix the TZ error codes and common problems.

Updated Jul 2, 2026Buy TZ

TZ is an internal utility, troll and PvP cheat for FiveM, made for a more relaxed or casual experience. It runs inside the game, so there is no complicated installation, and it has fewer settings than external software. Lifetime keys include a spoofer.

Requirements

Steam must be running.

Open Steam and log in before you start TZ.

Server build above 2600.

TZ only supports FiveM servers running a build above 2600.

Use the FiveM release version.

If you use the canary or beta version of FiveM, switch to the release version.

Register an account on the TZ Project website.

Redeem your key

Go to your account page, press Redeem Code, paste your key into the text box and press the checkmark. Your key is in your order email and on account.lmarket.net.

Inject TZ

Turn off your antivirus

Disable or uninstall your antivirus.

Run TZ

Make sure Steam is running, then run chrome.exe inside the TZ folder. Wait until it says "You can open the game ...".

Open FiveM and log in

Open FiveM. A menu pops up: log in with your TZ Project credentials.

Error #H01: Software issue detected

  2. If the issue remains, reinstall TZ and FiveM.

"P - Data Initialisation failed"

Join a different server with a higher build. Only builds above 2600 are supported.

"TZ Loader has been updated!"

  1. Download TZ again.
  2. Switch FiveM from canary/beta to the release version.
  3. If the issue remains, reinstall TZ and FiveM.

FiveM needs to restart

The server needs a specific FiveM build and pure mode. Create a FiveM shortcut that starts with them:

  1. Right-click the FiveM launcher and press Open file location.
  2. Create a shortcut to FiveM.exe and drag it to your desktop.
  3. Right-click the new shortcut, select Properties and open the Shortcut tab.
  4. At the very end of the Target box, type a space, then -pure_X -bYYYY.
  5. Replace X with the server's pure mode (for example 0, 1 or 2) and YYYY with the server build (for example 3095, 2699 or 2944). The restart message you get when joining the server shows both.

The target then looks like C:\Users\Axel\AppData\Local\FiveM\FiveM.exe -pure_1 -b2699, with your own path and values. Don't copy this example.

Crash while loading into a FiveM server
