Do you use TeamViewer to assist friends with their PC’s without charging them and yet you’ve received the “Commercial Use Suspected” message. This should get you running again.
[This tutorial is not intended to bypass TeamViewer’s paid services. If you use it commercially, please pay for it.]
If you have problems with getting TeamViewer working again, please state what version of TeamViewer as well as what version of Windows.
Currently, Windows 10 doesn’t seem to take this fix.
[when typing in any of the following, remove the ‘ from before and after the text]
- Uninstall TeamViewer using IObit Uninstaller or similar using the Powerful Scan (when installing IObit, make sure to deselect install Advanced System Care when the option comes up)
- Click Start then type %appdata% – now delete the TeamViewer folder
- Click Start the type %temp% and delete the contents of this folder as well as the X:\Windows\temp folder
- Click Start then type regedit, delete the registry folder at HKEY_CURRENT_USER\Software\TeamViewer & HKEY_LOCAL_MACHINE\SOFTWARE\TeamViewer if any
- Now change your MAC address, either manually or with a tool like TMAC [I suggest changing the MAC address on both network connections, i.e. wireless and LAN]
- [You can try without this step first to see if it works.] Open a Command Prompt with Administrator rights, browse to where you saved ‘sidchg.exe or sidchg64.exe’ and run sidchg.exe /f /r /key:3YPCr-vF9fi-R2VB7-ef for 32-bit or sidchg64.exe /f /r /key:3YPCr-vF9fi-R2VB7-ef for 64-bit Windows, make sure there is a space between the f and following / – Get the latest key from this page. SIDCHG can take a while to run. You might need to set your date to the previous month for SIDCHG to work.
- Your PC will restart automatically after running sidchg
- Install TeamViewer [You’ll see your PC has a new TeamViewer ID]

I’ve been thinking about setting TeamViewer up under a virtual machine using VirtualBox, just haven’t had a chance to play with it.
