How it works (step-by-step)
Purchase & get the program
After payment, you receive an activation key and a download link.
Requirements
Make sure you disable Secure boot from bios settings!.
Use a clean installation of Windows 10/11 Pro from the official Microsoft website.
Do not change Windows security settings (Firewall, UAC) and do not apply third-party “tweaks”.
Install a clean, unmodified Xentry / Daimler Truck.
Ensure it runs normally (no crashes, forced closes, or dumps).
Do not install any cracks, patches, or third-party activators.
Activation
On the first launch, FullFix will ask for an activation key. Paste the key and click “Activate”.
Use FullFix features
— If the activation key is accepted, you’ll see the component selection page.
— Do not select all components. Choose only what you need.
— Select the required components, click Next, and follow the on-screen instructions.
— After FullFix finishes, launch the program and sign in with:
Login: 11 Password: 22
One-time use
FullFix is a one-time tool for a single system. After it completes successfully, you don’t need to run it again.
If you later update the main program or reinstall Windows, you’ll need to purchase another activation key.
FAQ
Antivirus flags the app
Microsoft Defender is fine. If you use a third-party antivirus, temporarily uninstall it during installation and activation.
Can I move to another PC?
Activation is locked to one system at first run. To use another PC, you’ll need to purchase a new activation key.
Secure Boot is enabled
For proper operation, disable Secure Boot in your BIOS/UEFI settings.
If you’re unsure how to do this, search for “disable Secure Boot” plus your laptop/PC model.
The program says “No internet” or “Incorrect activation key”
The program requires an active internet connection to our server. If your network blocks the connection, try a different network or a VPN.
I installed FullFix but can’t find the Toolkit
If the main program is a newer version without SDConnect support, look for SDC4-VCI Switcher on the desktop.
This tool requires an internet connection to validate activation.
Run it and select the SDConnect mode.
If you have multiple adapters, better use only one. If your system HWID changes, SDC4-VCI Switcher will no longer work.
Which IP address should I use for SDConnect?
For SDConnect use the range 172.29.127.xxx. The xxx part can be any number from 1–254, except 129.
Example: 172.29.127.127.
For DoIP add an additional IP: 169.254.0.35.
The main program is not activated
If you already run FullFix and still see a “not activated” message, check that Secure Boot is disabled and run FullFix again with only the first (activation) component selected.
DTS Monaco freezes when i paste the activation code
If DTS Monaco freezes when you paste activation code, then just write it manually. Usually it's happening on Windows 11.
