If you have been using the free version of TeamViewer for personal and non-commercial purposes, you may have come across the frustrating “TeamViewer commercial use detected” error during a session. This error can abruptly end your session and leave you wondering what went wrong. It can be particularly concerning if you rely on TeamViewer to connect with family and friends or to access your work computer remotely.

In this article, we’ll discuss what causes the error, what TeamViewer considers personal and non-commercial use, and how you can fix the error in Windows 11/10 or macOS to continue using TeamViewer for personal purposes.

Why am I seeing “TeamViewer commercial use detected” or suspected?

TeamViewer offers two versions, one for personal and non-commercial use that is free, and another for business and commercial use that requires a subscription. If you have been using the free version and receive the “TeamViewer commercial use suspected” error, it indicates that TeamViewer has detected activity that may be considered commercial use. Some actions that may trigger the error include:

  • Connecting to your client’s or customer’s devices
  • Using TeamViewer for home office to check your emails or perform other actions
  • Letting your customers connect to your device
  • Monitoring devices running a server operating system such as Windows Server
  • Performing other actions that TeamViewer may suspect to be for commercial purposes

According to some users, connecting to too many devices from different locations around the world may also trigger the error.

What is considered personal and non-commercial use?

TeamViewer defines personal and non-commercial use as using the software to help family or friends remotely connect to their devices that are not running any server-like operating systems and are not being used in any commercial environment.

For example, you may use TeamViewer to help your family members troubleshoot issues with their computers or to help a friend with a technical problem. Additionally, if you work from home and use TeamViewer to connect to your office computer to access personal files or check emails, it would still be considered personal and non-commercial use as long as your computer is not connected to a commercial environment, such as a business network.

It is important to remember that using TeamViewer for commercial purposes, such as connecting to your clients’ or customers’ devices or monitoring devices running server operating systems, requires a paid license. If you use TeamViewer for commercial purposes and continue to use the free version, you may receive the “TeamViewer commercial use detected” error and risk having your account switched to the commercial version or even being blocked.

How can I fix the “TeamViewer commercial use detected” error?

If you have received the “TeamViewer commercial use detected” error and are confident that you are using TeamViewer only for personal and non-commercial purposes, there are a few things you can try to fix the error.

First, you can attempt to do a complete uninstall and reinstall of the free version of TeamViewer on your computer. Refer to this guide: “How to fix TeamViewer trial version expired” for detailed instructions on how to do this.

Finally, if you are using TeamViewer for commercial purposes, it is crucial to purchase a license to avoid any interruptions in your work. TeamViewer offers various licensing options, so be sure to choose the one that best suits your needs.

It is important to note that if you receive the “TeamViewer commercial use detected” error and you are using the software for commercial purposes, you should not try to fix the error by uninstalling and reinstalling the free version. Doing so is a violation of TeamViewer’s terms of service and can result in your account being blocked.
