How to Reset TeamViewer ID?

7.2K

After installing TeamViewer and its first connection to the network, the program receives a unique identification number (ID). It allows remote users to perform a remote connection to your computer, and vice versa. If you are using a free version of TeamViewer to connect to different computers (for commercial purposes), there is a high probability that your remote connections via the TeamViewer will be limited to a value not exceeding five minutes, after which the connection will be terminated.

Understanding the TeamViewer Commercial Use Detection

TeamViewer ID is generated based on several unique attributes of your device:

• MAC address of the network card;
• VolumeID of disk partition;
• Creation date of the Program Files folder.

How TeamViewer Generates the Client ID

Historically, TeamViewer ID was generated using several hardware and system identifiers (including the network adapter MAC address, disk Volume ID, and certain filesystem metadata). On recent TeamViewer versions, the exact algorithm is proprietary and may include additional hardware identifiers, so changing these values does not always result in a new TeamViewer ID.

If the TeamViewer online service decides you are using the tool for commercial purposes to connect to multiple customer computers, a warning window may appear:

Your trial period has expired

Commercial Use Error in TeamViewer v14

The commercial use message in TeamViewer v14 looks as follows:

Commercial use detected

This software seems to be used in commercial environments. Please note that the free version may only be used for personal use.

Your session will be terminated after 5 minutes.

Commercial Use Error in TeamViewer v15

In TeamViewer version 15, the message about the restriction on using your copy of TeamViewer has changed:

We are sorry for the interruption.

Your connection has been blocked because of very high activity level.

We appreciated your interest, but our software must be licensed for professional work. Please follow the button to purchase a license to continue.

The trial version TeamViewer expiration message usually appears after a couple of days when using the utility.

In this case, you can try to reinstall the TeamViewer, but that won’t help you. One possible workaround is resetting the TeamViewer ID, although this method may not work on recent TeamViewer releases because the product uses additional hardware and device identifiers.

You can see your TeamViewer ID on the main screen when running the application.

TeamViewer Versions: Trial Expiration Problem

• Free version (non-commercial use) — designed for home use and connecting to a small number of remote devices;
• Paid (commercial) version — the number of connected devices and the duration of the sessions are unlimited.

If you use TeamViewer for personal use only, here’s how to fix the TeamViewer trial expired problem.

Make sure that you and the users you connect are using the free version of TeamViewer. If one user uses a free one and the second uses a commercial one, then the commercial version will consider the use of TeamViewer for commercial purposes.

Preliminary Steps: Uninstall & Clean Slate

If the commercial version of TeamViewer is installed, you need to remove it, clear the registry and folders from the remaining entries and files. Then install the free version of TeamViewer.

Remove TeamViewer and Clear AppData

1. Go to Add or remove programs, find TeamViewer in the list, and select Uninstall;

   

2. After removing the program, press Win+R > %Appdata% > OK. Remove the folder TeamViewer;
3. Then delete the directory C:\Program Files\TeamViewer;
   

   

4. In a safe way remove the TeamViewer folder %USERPROFILE%\AppData\Local;

Delete Registry Entries (ClientID, HKCU, HKLM)

Remove the following registry key using the Registry Editor (regedit.exe): Computer\HKEY_CURRENT_USER\Software\TeamViewer, Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\TeamViewer, and HKLM\SOFTWARE\TeamViewer.

Now reboot your machine.

Verify Clean State

Download and install the TeamViewer free edition (press “Free Download: Free For Private, Non-commercial Use” on TW site).

If this does not work, move on. There is another more difficult way to extend the TeamViewer usage by resetting the TeamViewer ID.

Reset or Change TeamViewer ID in Windows

To reset the TeamViewer ID on Windows 10, you need to perform a few steps as described below.

Stop TeamViewer Services & Processes

First of all, kill the TeamViewer.exe process and stop the Team Viewer service (net stop Teamviewer). Then you need to remove the current TeamViewer ID from the registry.

Delete Registry ClientID (x86 & x64)

In Windows x86, TeamViewer version [X], open regedit.exe, go to the registry key HKLM\SOFTWARE\TeamViewer\, and delete DWORD value ClientID;

In Windows x64, delete value ClientID from HKLM\SOFTWARE\Wow6432Node\TeamViewer.

Check if the registry key HKEY_CURRENT_USER\Software\TeamViewer exists and delete it.

Change “Program Files” Creation Date (using NirCMD)

Open the PowerShell console with administrator permissions and check the creation date of the “C:\Program Files” folder:

Get-Item "C:\Program Files" | select Name,CreationTime

Older TeamViewer versions used the creation timestamp of the Program Files directory as one of several inputs when generating the client ID. To change the creation date of the Program Files folder, you can use the NirCMD tool (https://www.nirsoft.net/utils/nircmd.html). Download it and run the following command in the elevated Command prompt console:

nircmdc.exe setfilefoldertime "C:\Program Files" now now

Check if the CreationTime value of the directory has changed.

Change MAC Address via Registry

To change the MAC (physical) address of the network card, you can use special tools, or use the following instructions for manually editing the MAC address through the registry.

To get the current MAC address of your network card, open command prompt, and run the following command:

Ipconfig /all

We are interested in two parameters:

• Description (LAN card description) — Intel(R) 82574L Gigabit Network Connection;
• Physical Address (MAC address) — 00-0C-29-9D-4D-81

Then, open the Registry Editor and go to the key HKLM\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}.

Each network component in this registry key is indicated by four digits starting from 0000, 0001, and so on. You can find the right key by browsing it, and looking for DriverDesc option, where the description (name) of your NIC must be specified (for example, Intel(R) 82574L Gigabit Network Connection).

Once the correct network card is found, you need to add or modify REG_SZ parameter named NetworkAddress. It defines the MAC (hardware) address of the network card. It is enough to change a single digit in the current MAC address—for example, 000C299D4D80.

Hint. Also, you can list your NICs with MAC addresses using a simple PowerShell one-liner:

Get-CimInstance Win32_NetworkAdapterConfiguration |
Select-Object Description, MACAddress

Change VolumeID using VolumeID Tool

So, the MAC address of the network card is changed. Now you need to change the VolumeID of the system partition. VolumeID (or Volume Serial Number) is a unique identifier of a volume on a hard drive, which is set during formatting.

To change VolumeID, use the console utility VolumeID v2.1. Download and extract archive VolumeId.zip.

Check the current VolumeID by opening a command prompt with Administrator privileges, and execute the command:

vol

Volume Serial Number is 5E37-ECE1.

Change the current value to new value 5E37-EC11:

Cd c:\users\root\Downloads\VolumeID

Volumeid.exe c: 5E37-EC11

Reboot & Confirm New ID in TeamViewer

OnceVolumeId utility updated the volume serial number of your system partition, close the Command Prompt window, and reboot your computer.

After rebooting, run the app, and you will be assigned a new TeamViewer ID.

How to Reset TeamViewer ID on Linux?

In case you are using TeamViewer on one of the Linux distributions, you can follow the instructions below to reset the TeamViewer ID. The method is tested on Debian 9, and with some modifications, you can use it on any Linux distribution.

Uninstall & Remove Machine-id File

1. Uninstall Teamviewer with su privileges;
2. Remove the file /var/lib/dbus/machine-id if it’s exist;
3. Edit the GUID (you can just replace the last character): mc -e id.txt

Modify MAC Address via ifconfig / ip commands

1. Change the MAC address of the network card:
   

   ifconfig eth0 down
   
   ifconfig eth0 hw ether New_MAC_HERE
   
   ifconfig eth0 up
   
   nano /etc/network/interfaces

2. Correct string:
   

   pre-up ifconfig eth0 hw ether New_MAC_HERE

   
3. Reboot OS.

Note that on modern Linux distributions, the ip command is preferred over ifconfig, although both may work depending on the installed networking tools.

Reinstall TeamViewer & Generate New ID

Install Teamviewer, it should get a new ClientID.

Linux Mint distro

In the Linux Mint distro, you can reset TeamViewer ID as follows:

1. Delete TeamViewer:
   

   sudo dpkg -r teamviewer

2. Remove the binding file (if exists):
   

   sudo rm /var/lib/dbus/machine-id

3. Change the NIC’s MAC address;
4. Install the TeamViewer package again:
   

   sudo dpkg -i teamviewer_13.2.13582_amd64.deb

5. If an error with the missing packages occurs, run the command:
   

   sudo apt-get install -f

To change the ClientID on a cloned Linux machine it’s enough to:

1. Stop the TeamViewer daemon:
   

   systemctl stop teamviewerd

2. Delete TeamViewer settings:
   

   rm -r ~/.teamviewer

3. Remove folder /opt/teamviewer{TW_VERSION_Here)/config;
4. Start the TeamViewer daemon.

How to Change TeamViewer ID on Mac OS?

To change the TeamViewer ClientID on the Mac OS, you can use the python script TeamViewer-id-changer.py from GitHub. Follow these steps:

1. Download script from Git Hub;
2. Close the TeamViewer (make sure the TeamViewer process has completely disappeared from the processes list);
3. Run the script:
   

   sudo ./TeamViewer-id-changer.py

4. Reboot the device.

This script works correctly for TeamViewer 11, 12, 13, 14 and 15.

Additional Hints to Reset the TeamViewer ID

In TeamViewer 15, the developers are significantly changing the way the TW ID is generated. If tips above didn’t work as expected, try one of the following:

• Install the old version of TeamViewer (11, 12, or 13), reset it according to the article, and try to update the TeamViewer version;
• You can create a virtual machine to use Team Viewer. Take a snapshot and install TeamViewer. If your TW ID is locked, simply revert your virtual machine to the previous snapshot and install TeamViewer from scratch.

Legal Reminder

We recommend you to use and download only official software.
