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 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. Hi Grant, Thanks for the information.
TeamViewer is free for personal use, but you’ll have to buy a license if you are using it for commercial purposes. Off late I had a few readers e-mailing a common problem they had with TeamViewer. The common problem was that, even though these visitors were not using TeamViewer for commercial purpose they were getting the following message. 4 easy steps on how to solve TeamViewer 'Comercial Use Suspected' Problem, FAST and QUICK.

I would just like to add that most built in network adapters on computers will display the “ Network Address“, However if you have a ‘ wifi / wireless) card it may say ‘ Locally Administered MAC Address‘. See link for some information about So basically watch out for the ‘ wifi / wireless‘alternative. Install microsoft office 2015 for mac. I never heard of TMAC so thanks for suggesting it.
The program i used for years was called SMAC. Here is a quick video to show how it works. PS Sure wish i had the option to preview this post before sending it.
Link Sources: LAA / Locally Administered MAC Address: Smac: •. If it factual that ‘does not work’ then sorry I can’t help but if is more accurately ‘I couldn’t get it to work’ then there is a possibility of trying it again with modifications and it then working As I said in my last comment I tested it and modified the sequence a little and it worked for me. I decided to add the additional steps of clearing%temp% and the x: windows temp folder to make sure nothing was being stored there. I also ran TMAC after rebooting instead of before. I’ll test again on another system to see if I can replicate my results. Worked fine, but only for once in my case. Let me explain: The goal is to change the teamviewer ID, and in order to do you have to remove all the above mentioned files (see above or even use a teamviewer portable version that doesn’t saves anything on the disk) and then change the MAC address of your NIC.
There is possibility to provice another MacAddress in my nic driver (properties, advanced, network address). So I changed the macaddress I got indeed a new teamviewer id and it worked again for 2-3 weeks. This new teamviewer ID is now also blocked, so I decided to redo the same procedure and change again the mac address of the nic via the driver. And there start the problem: I discovered that if I change the mac address of the nic once again, the teamviewer ID doesn’t change anymore.
If I remove the manual mac address, I come back to the original mac of the nic and to the teamviewer id blocked 3 weeks ago. So for me, I have one specific teamviewer ID (let’s call it ID1) on the original mac address, and another teamviewer ID (let’s call it ID2) whatever the manual mac I choose in the driver. So the trick to change the macaddress saved me once, but it doesn’t seems to work anymore: whatever mac I manually install I get ID2 in teamviewer, if I remove it, I get ID1.
Could it be linked to the driver of my Dlink Nic? Any other trick to change the mac address? Upgrades for office 2010 for mac. Thanks Grant for your answer. The PC I use is a good old desktop with an ethernet dlink NIC. No wireless card. I just tried with TMAC and got exactly the same problem.
I always get the same Teamviewer ID with the “original” burned-in MacAddress of the dlink NIC. If I change the MacAddress within the dlink driver or with TMAC, I get another Teamviewer ID, but always the same whatever the “software” MacAddress I choose. (and I’m sure the MacAddress is really changed with the driver and with TMAC since I see the different MacAddresses I create in the DHCP log of my DSL-Box/router). So for me, the original TeamViewer ID corresponding to my “real” MacAddress is blocked by TeamViewer. The other ID (the one I get whatever soft MacAdress I choose) is now also on the black list so I’m blocked I can quickly change back and forth from original to modified mac and each time I start teamviewer I see the ID changing from one to the other (so it’s not that there is a setting somewhere that blocks me on the same teamviewer ID but again I see only two different ID and both are on the teamviewer black list). I removed all the items following the procedure described (it worked the first time). I also tried with the portable version of teamviewer (), same problem.
