After installing TeamViewer and first connection to the network, 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 (commercial purposes), here is a high probability that your remote connections will be limited on the TeamViewer server to a value not exceeding five minutes, after which the connection will be terminated.
If the TeamViewer servers decide that you are using the utility for commercial purposes to connect to multiple customer computers, a warning window may appear:
Your trial period has expired
The commercial usage 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.
The trial version TeamViewer expiration message usually appears after a couple of days of use.
In this case, you can try to reinstall TeamViewer, but that won’t help you. The only way to unblock the limitation is to reset TeamViewer ID (or purchase a license ).
You can see your TeamViewer ID on the main screen when running application.
TeamViewer Versions: Trial Expiration Problem
There are two TeamViewer versions:
Free version (non-commercial use) — designed for home use and connecting to a small number of PCs;
Paid (commercial) version — the number of connected PCs 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 are connecting 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 in the commercial purpose.
If the commercial version of TeamViewer is actually installed, you need to remove it, clear the registry and folders from the remaining entries and files, and install the free version of TeamViewer.
Go to Add or remove programs, find TeamViewer in the list and select Uninstall;
After removing the program, press Win+R > %Appdata% 0 > OK. Remove the folder TeamViewer;
Then delete the directory C:\Program Files\TeamViewer;
Delete the following registry key using the Registry Editor (regedit.exe): Computer\HKEY_CURRENT_USER\Software\TeamViewer and Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\TeamViewer
Reboot your computer;
Download and install the TeamViewer free edition (press “Download for free” on TW site);
If this does not work, move on. There is another more difficult way to extend the TeamViewer usage by resetting TeamViewer ID.
TeamViewer ID is generated basing on several unique attributes of your computer:
MAC address of the network card;
VolumeID of disk partition;
Creation date of folder Program Files.
Accordingly, in order to change TeamViewer ID, you need to change these 3 values.
Reset or Change TeamViewer ID in Windows
To reset the TeamViewer ID, you need to perform a few steps.
First of all, kill the TeamViewer.exe process. Then you need to remove current TeamViewer ID from the registry.
In Windows x86, TeamViewer version [X], open regedit.exe, go to the registry key HKLM\SOFTWARE\TeamViewer\Version[X] and delete DWORD value ClientID;
In Windows x64, delete value ClientID from HKLM\SOFTWARE\Wow6432Node\TeamViewer\Version[X];
Check if the registry key HKEY_CURRENT_USER\Software\TeamViewer exists and delete it.
To change the creation date of Program Files folder, you can use the NirCMD utility. Download it and run the following command in the elevated Command prompt console:
To change MAC address of the network card, you can use special utilities or use the following instructions for manually edit MAC address in registry.
To get the current MAC address of your network card, open Command prompt and run the following command:
We are interested in two parameters:
Description (LAN card description) – Intel(R) 82574L Gigabit Network Connection
Physical Address (MAC address) – 00-50-56-9E-FC-CB
Then, open Registry Editor and go to the key HKLM\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}.
Each network component in this branch 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 must be specified the description (name) of your NIC, for example: Intel(R) 82574L Gigabit Network Connection.
Once the correct network card is found, add or modify REG_SZ parameter named NetworkAddress, which defines MAC (hardware) address of the network card. It is enough to change a single digit in the current MAC address, for example 0050560EFCCB.
So, MAC address of the network card is changed. Now you need to change VolumeID of system partition. VolumeID (or Volume Serial Number) is a unique identifier of a volume on hard drive, which is set during formatting.
Note. In some cases, TeamViewer is linked to a non-system volume of disk, or even to the removable media volume, so it is likely that we need to change VolumeID of other partitions.
To change VolumeID use the console utility VolumeID v2.1. Download and extract archive VolumeId.zip.
Check the current VolumeID by opening command prompt with Administrator privileges and execute command:
Volume Serial Number is 5E37-ECE1.
Change current value to new value 5E37-EC11:
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 in order 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 Teamviewer with su privileges;
Remove the file /var/lib/dbus/machine-id if exist;
Edit the GUID (you can just replace the last character): mc -e id.txt;
Change the MAC address of the network card:|
Correct string:
pre-up ifconfig eth0 hw ether New_MAC_HERE
Reboot OS;
Install Teamviewer, it should get a new ClientID.
In the Linux Mint distro, you can reset TeamViewer ID as follows:
Delete TeamViewer:sudo dpkg -r teamviewer
Remove the binding file (if exists): sudo rm /var/lib/dbus/machine-id
Change the NIC’s MAC address;
Install the TeamViewer package again: sudo dpkg -i teamviewer_13.2.13582_amd64.deb
If an error with the missing packages occurs, run the command: sudo apt-get install -f
To change ClientID on a clonned Linux machine it’s enough to:
Stop the teamviewer daemon;
Delete teamviewer settings:
Remove folder /opt/teamviewer{TW_VERSION_Here)/config;
Start the teamviewer daemon.
How to Change TeamViewer ID on Mac OS?
To change TeamViewer ClientID on the Mac OS, you can use the python script TeamViewer-id-changer.py from GitHub. Follow these steps
Download script from Git Hub;
Close TeamViewer (make sure the TeamViewer process has completely disappeared from the process list);
Run the script: sudo ./TeamViewer-id-changer.py;
Reboot the device.
This script works correctly for TeamViewer 11, 12, 13 (not tested in TeamViewer 14).
If reinstalling and resetting TeamViewer ClientID did not help you, and you are absolutely sure that you are using TeamViewer for personal use only, you can create ticket request using the online form to unlock your device (https://www.teamviewer.com/en/support/commercial-use-suspected/). Fill the form, specify a specific TeamViewer ID from your device and send a request.
After a while (3-5 days), TeamViewer support will answer on your request: your device will be unlocked or your “commercial use” label will remain for your ID. If you really use TeamViewer for commercial purposes, buy a license, or try another free remote product to manage your users and customers.
