If you are attempting to use your Ross-Tech VCDS (VAG-COM) interface and have encountered a message stating "License Revoked," "Interface Not Found," or "Interface Invalid," your device has been flagged by the Ross-Tech server.
This issue typically prevents the software from communicating with the vehicle. Below is a breakdown of why this happens, the specific steps to fix it, and how to distinguish a genuine Ross-Tech cable from a cloned one.
The "Revoked" status is a security measure implemented by Ross-Tech to protect their intellectual property. The causes generally fall into two categories depending on whether you own a genuine cable or a counterfeit clone.
Rarely, aggressive antivirus (Norton, McAfee) or a Windows update will block VCDS from "phoning home." The software then assumes the lack of response means you are using a clone, so it self-revokes.
VCDS.exe and Ross-Tech.com in your firewall and antivirus. Uninstall the software, reboot, and reinstall the latest version from Ross-Tech’s official website (not the CD that came with your cable).This is the most common scenario. Counterfeit cables (often sold cheaply on eBay, AliExpress, or questionable Amazon sellers) attempt to mimic genuine Ross-Tech hardware.
If you are searching for a "fix" because your VCDS cable suddenly stopped working and shows a "Interface Revoked" or "Interface Not Found" error, there is no safe software patch or crack.
This is almost exclusively an issue with counterfeit (clone) cables. Ross-Tech (the software developer) has implemented security measures that brick these fake cables remotely or via firmware updates.
Summary of the Fix:
The "Status: Revoked" error in VCDS typically indicates that a non-genuine (clone) interface cable has been detected and deactivated by the official
. This often happens if the computer connects to the internet and the software automatically updates or checks the cable's serial number against a blacklist. Common Causes Software Updates
: Using a clone cable with a version of VCDS downloaded directly from Ross-Tech instead of the specific "cracked" version it came with. Internet Access
: Allowing the software to "phone home" while the cable is plugged in, which triggers a license check. VIN Limits
: On genuine cables, this status might appear if a limited-VIN interface has reached its maximum number of registered vehicles. How to Fix "Status: Revoked" 1. Perform a Full Software Reinstall
have reported success by completely wiping the software and drivers before reinstalling:
Uninstall VCDS and delete all remaining files from the installation folder. Device Manager
, find the cable (often under "Universal Serial Bus controllers" or "Ports"), and uninstall the driver.
Reinstall the specific version provided by your cable vendor. Some users found success installing the 32-bit version even on 64-bit systems. 2. Forced Firmware Reflash (For Genuine/High-End Cables) If you are using a genuine HEX-V2 or HEX-NET
that is stuck in a "revoked" or "questionable" state due to a failed update: VCI Config utility
(click the "Net" button on the VCDS main screen, then "Config"). tab and click Check for updates
Force a "Download update" even if it says it is current; this can overwrite corrupted firmware. 3. Hardware-Level Reset (For Clones)
If the cable is a "brick" (no longer recognized at all), it may require reflashing the internal chip (e.g., Firmware Loaders
: Some communities provide "Loader" archives (like Loader 9.2) that can reflash the EEPROM to reset deactivation. Hardware Replacement vcds revoked fix
: In many cases, once a clone cable is blacklisted by official software, the easiest fix is to replace the interface and ensure future sessions are done with Wi-Fi disabled or through a Virtual Machine with no network access. Prevention Tips Block Internet : Create a Windows Firewall rule to prevent from accessing the internet. Disable Auto-Updates
: Never click "Yes" when the software prompts you to update if you are using a non-genuine cable. Use Provided Software
: Only use the version of VCDS that came on the CD or download link provided by the cable seller. create a firewall rule specifically to block VCDS from the internet?

The "Revoked" license status in VCDS typically occurs when the software detects an unauthorized or "clone" interface, or if a genuine device's internal security certificates have expired or been flagged. For Genuine Ross-Tech Interfaces
If you are using a genuine interface, a revoked status is usually a technical glitch or a result of a failed firmware update.
Force a Firmware Update: Access the VCI Config utility by going to "Options" then clicking the "Config" button. Go to the "Update" tab and click "Check for Updates" then "Download Update". This can often reset the interface and restore the license.
Contact Official Support: If the device remains revoked, genuine users can contact Ross-Tech Support with a screenshot of their "About" screen to have the license manually reinstated. For Non-Genuine (Clone) Interfaces
"Revoked" is a common defense mechanism in official Ross-Tech software when it detects pirated hardware. Once revoked, the cable is often "bricked" and cannot be easily used with newer software versions.
Offline Isolation: To prevent this, clone users often use an older laptop that is permanently disconnected from the internet or set a firewall rule to block the VCDS executable from connecting to the web.
Loader Usage: Some third-party "loaders" claim to bypass the license check, but these are often unstable and may contain security risks.
Firmware Reflash: Expert users sometimes attempt to reflash the interface's EEPROM with a known good serial number (like RT000001), though this is difficult and often unsuccessful once the software has flagged the hardware.
If your genuine interface has lost its connection, you can often restore it by forcing a firmware update through the VCI configuration utility:
A "License Revoked" error in VCDS typically occurs if a clone (non-genuine) cable is used with a newer software version or if it attempts to connect to the internet, causing Ross-Tech's servers to flag and "kill" the interface's internal chip. 1. Identify the Cause
Clone Interfaces: Most "revoked" cases involve clone HEX-V2 or HEX-CAN cables. Newer VCDS software can detect these and overwrite the cable's firmware to disable it.
Failed Firmware Update: Genuine cables can also appear "revoked" or "stuck" (indicated by flashing red lights) if a firmware update was interrupted. 2. Fixing a Genuine Cable (Ross-Tech)
If you own a genuine interface, you can usually fix this by forcing a firmware refresh.
Open VCDS Config: Launch VCDS and click on Options, then Config. Access Update Tab: Navigate to the Update tab.
Force Update: Click Check for updates. If it finds an update, click Download update. This often resets the license state to "Valid" after a successful flash.
Test on Car: Plug the interface into a vehicle's OBD-II port (this provides 12V power) and run a Test in the Options menu to confirm status. 3. Fixing a Clone Cable (Blocked/Revoked)
If your clone cable is revoked, it is often "bricked" at the hardware level. Some community-sourced methods may work to reactivate it: VCDS "License Revoked" Error: Complete Diagnosis and Fix
Uninstall VCDS: Remove the current version of VCDS entirely.
Disable Internet & Antivirus: Disconnect your laptop from the internet and disable Windows Defender/Antivirus, as they often delete the "loader" files required for clones.
Use a Loader: Clones typically require a specific VCDSLoader.exe file.
Reinstall the VCDS version that originally came with your cable.
Copy the loader file into the Ross-Tech installation folder.
Always launch the software using the loader shortcut, never the original VCDS.exe.
Registry/Date Hack (Last Resort): Some users attempt to set their PC date back 1–2 years to bypass license checks, though this is rarely successful for revoked statuses. 4. Preventing Future Revocations
Block in Firewall: Use Windows Firewall to block VCDS.exe from accessing the internet.
Turn off Auto-Updates: In VCDS Options, set the "Check for Updates" frequency to "Never". Offline Use: Only use the diagnostic laptop while offline.
For genuine Ross-Tech cables showing errors, follow this guide to force a firmware update and restore functionality:
The "VCDS Revoked" error typically occurs when the software detects an unauthorized or "cloned" interface cable. Ross-Tech, the developer of VCDS, implements security checks that can "revoke" the license stored in the cable's firmware if it's determined to be counterfeit. Common Fixes for a Revoked License Description Recommended For Verify Connection
Ensure the cable is firmly plugged into both the laptop and the car's OBD-II port. Sometimes a poor connection mimics a revocation error. Check Internet
Modern VCDS versions occasionally require an internet check to validate the license. Connect to Wi-Fi and try the Test button in the "Options" menu. Genuine cable users Update Software
If you have a genuine cable, download the latest version from the official Ross-Tech website. Genuine cable users The "Clean Install"
Uninstall VCDS, delete the remaining folder in C:\Ross-Tech, and reinstall. This clears cached license data that might be stuck. Persistent software errors Why License Revocation Happens
Clone Interfaces: If you purchased a low-cost cable from a non-authorized third party, VCDS may identify it as a clone and permanently disable it via a firmware "kill switch".
Version Mismatch: Using a newer version of the software with an older or "cracked" cable often triggers the revocation.
Firmware Corruption: On rare occasions, a legitimate cable's firmware can become corrupted during an update, requiring a reset through the software's internal diagnostic tool. Advanced Diagnostic Steps
If the license shows as "Revoked" or "Invalid" in the About screen: Go to Options -> Test.
Observe the "Interface" results. If it says "Interface Not Found," it’s likely a hardware or driver issue.
If it says "Revoked," the firmware has been flagged. For genuine users, contacting Ross-Tech support with your serial number is the only way to restore the license. Solution: Whitelist VCDS

The "VCDS License Revoked" status is a common and frustrating error that prevents you from using your Ross-Tech interface for vehicle diagnostics. This typically occurs when the software detects hardware it believes is illegitimate or if a firmware update has failed, leaving the device in a "bricked" or locked state. Why Your VCDS License Was Revoked
Understanding the root cause is the first step toward a fix. Most revocations fall into two categories:
Clone Hardware Detection: If you are using a non-genuine "clone" cable from sites like eBay or AliExpress, newer versions of the official Ross-Tech software are designed to detect and disable these devices. Once the software communicates with the official servers and identifies a blacklisted serial number, it "revokes" the license stored on the cable's chip.
Corrupted Firmware Update: For genuine users, a failed or interrupted firmware update can trigger a revocation or an "Interface Not Found" error. This often happens if the USB cable is unplugged during an update or if the computer loses its internet connection mid-process.
Driver & Chipset Interference: Occasionally, other diagnostic software may overwrite the data on the FTDI chipset used by Ross-Tech devices, causing the software to no longer recognize the interface as valid. How to Fix a Revoked VCDS License 1. The "Force Update" Method (For Genuine Cables)
If you have a genuine HEX-V2 or HEX-NET interface, you can often "un-revoke" the license by forcing a fresh firmware update through the Ross-Tech VCI Config Utility: Connect your interface to your PC via USB.
Open VCDS and click Options > Config (or use the standalone VCI Config tool). Navigate to the Update tab and click Check for updates.
If the utility detects the interface, click Download Update.
Important: Wait for the lights on the interface to turn blue, indicating a successful reset. 2. Driver Reinstallation and Rollback
Sometimes Windows updates install generic drivers that conflict with the Ross-Tech hardware. Go to Device Manager on your PC.
Locate the Ross-Tech interface under "Universal Serial Bus controllers" or "Ports (COM & LPT)."
Right-click and select Uninstall device, then unplug the cable.
Download the latest software directly from the official Ross-Tech site and reinstall it, which will refresh the correct drivers.
Plug the cable back in only after the software installation is complete. 3. Fixing Clone Cables (The "Offline" Fix)
If you are using a clone and the license has been revoked, the "bricking" is often permanent unless you have advanced technical skills to flash the EEPROM chip. To prevent this or potentially recover a partially blocked cable:
Disconnect from the Internet: Always disable Wi-Fi before opening VCDS if you are using a clone.
Firewall Block: Create a rule in your Windows Firewall to prevent the vcds.exe file from communicating with the internet.
Use Specific Software Versions: Many clones are only compatible with the specific (often patched) version of the software they were shipped with. Avoid updating to newer versions from the Ross-Tech website. 4. Contacting Support or Registering
If your genuine device was purchased secondhand and shows as revoked, you may need to pay a registration fee to Ross-Tech to transfer the license to your name and regain full functionality and support. Pro Tips for Prevention YouTube·Gendan Swansea
