Install or Reinstall TeamViewer 11/12/13 Personal (Non-Commercial) License on Windows Server (2012/2012 R2/2016 etc) [Updated Dec 2017]

After running out of the TeamViewer commercial trial period I sought to find a solution to the problem of having to buy an expensive licence for my home server (which is only used for non-commercial personal use).

[Update Dec 2017]: I can confirm that these procedures still apply and work with Teamviewer version 12 and 13 also (as tested on Windows Server 2016).


Procedure A: If TeamViewer is NOT Already Installed (Note: If it is already installed, then first follow procedure B. below)

  1. Download and Run the installer downloaded from http://www.teamviewer.com/. On the Welcome to TeamViewer page be sure to check the "Show advanced settings" check box (outlined in red at bottom left in picture), then click "Accept - next".
  1. Leave the "Advanced settings" installation window open (as shown above) and start Windows Explorer (i.e. the file manager, not Internet Explorer). Now go to your temp directory by typing "%tmp%" into the location bar and hitting enter.
  2. Go to the Detailed view (View -> Details), and sort at the Date modified column.
  3. Open the nsxXXXX.tmp directory (where the Xes are some random characters/numbers)
  4. Inside that directory open the "start_unicode.ini" file with Notepad or Notepad++.
  5. Change the value of Flags= key item in [Field 5] and [Field 4] by swapping their values between DISABLED and GROUP|NOTIFY so you have Flags=GROUP|NOTIFY in [Field 5].
  6. Then also swap the values of the State= item of [Field 5] and [Field 4] so that only [Field 5] has the value of State=1 (i.e. Field 4 must be 0).
  7. Save and close the file.
  8. Maximize your TeamViewer installation window again and click "Finish" to complete the installation.

Procedure B: If TeamViewer is already installed (i.e. Commercial Trial version)


  1. Uninstall TeamViewer (best way is to use CCleaner)https://www.piriform.com/ccleaner/download 
  2. Click Start then type ‘%appdata%’ – now delete the Teamviewer folder
  3. Click Start the type %temp% and delete the contents of this folder as well as the C:\Windows\temp folder
  4. Click Start then type ‘regedit’, delete the registry folder found at HKEY_CURRENT_USER\Software\TeamViewer & the folder HKEY_LOCAL_MACHINE\SOFTWARE\TeamViewer
  5. (Choosing remove settings when uninstalling is also sufficient)
  6. Then goto C:\Users\(Your username)\AppData\Roaming  > delete the Teamviewer folder [you might have to make hidden folders visible to see it or just type the path into the address bar]
  7. NOTE: Previous procedures request you restart your PC at this point. My testing did not find this was necessary.
  8. Now change your MAC address, either manually or with a tool like TMAC
  9. https://technitium.com/tmac/
  10. YOU MUST change ALL the MAC address on multiple network interface connections including virtual ones (i.e. as used by Hyper-V or other hypervisors)
  11. Now Re-Install TeamViewer [You should see your PC has a new TeamViewer ID] AS PER THE PROCEDURE ABOVE.  YOU MUST DO IT THIS WAY!
  12. NOTE: Some previously published procedures request you restart your PC at this point this is not usually necessary in my experience to test.

BEWARE! If you run later TeamViewer updates without following Procedure A above you will likely need to follow Procedure B again later with the down side of again having to change all the NIC MAC addresses again :-(

Note: The procedures were developed and modified from these previous ones...

NOTE: These methods also work on HyperV Server 2012 and 2012 R2 with the exception you will need to install Explorer++ (or other independent file manager) first.

there is a much simpler method:

1- uninstall temaviewer 11 (normally)
2- download version 8, since other old versions don't work for this purpose (from here for example http://www.oldversion.com/windows/teamviewer-8-0-16642)
3- be sure to check "compatibility mode windows xp" before installing it, and then, during the installation "advanced options" and "personal use only". When installed and "licensed" you can then remotely upgrade to version 11 without any issue..

Hi CANE thanks greatly for that feedback. Your alternative, possibly simpler (certainly less technical), approach to procedure A makes me wonder if the remote upgrade avoids the licence re-check than the local update/upgrade process does? I will have to try that some time if I ever get an opportunity and remember. I still think you will need to run the second procedure B if your TeamViewer ID (which is based on your PC's MAC addresses) has been blacklisted as "commercial" in the TeamViewer database as the record is kept out there on the cloud rather than on the PC (hopefully that record expires at some point).

Also a more legitimate (and trustworthy) source of previous versions of TeamViewer can be got from here:

I have now tried CANE's method by installing TeamViewer 8 first and it did not seem to work for me, i.e. I got locked out of TV free after a trial period. But that might be because the MAC Addresses of my server where already registered online. So I guess that approach might still work if done from the outset.

The procedure (A) is not working on Server 2016. :/
Rsi Gondanglegi said…
Thanks Mr Rod Dines, it's work on my server's company.
Rod Dines said…
@RodDines[My last post] - Since the lockout eventually the commercial trial reverted to a free trial on TeamViewer 8 and works again now. I am going to leave it this way as TV11->TV8 remote control works fine (it will not work the other way though ie TV8->TV11)
@Junior - I haven't yet tried with Server 2016 but when I do I will post again.
@Rsi - Glad it worked for you!

I uninstalled Ver 11, did a CC clean, Did a search and deleted all teamviewer in Regedit, installed ver 8, remoted in and upgrade and it said my license had expired. I uninstalled ver 11 and am going to just leave it ver 8. I contacted Teamviewer support a couple of days ago and have not heard back from them. That would make me less likely to buy their product. Just send me a email on how you think I should do it, I am sure they have a procedure to completely uninstall or someone has written a program to do it.
Rod Dines said…
@aintright The problem is associated with how TeamViewer track licences independently of the installation as such. The license is associated with the link between you PC's network hardware/software addresses (MAC addresses) and their own license database. You can create a new record database index) by forcing a change in the MAC addresses using the Procedure B in the post. Then follow procedure A and the install should work as a non-commercial license. But you may find that leaving version 8 will work over time as I have recently commented on above. Interestingly a lot of traffic to this blog from Germany (where the TeamViewer software is maintained) about 2 months back (none or little before that nor since) might reveal that the publishers after becoming aware of this work-around have potentially changed later versions of the TeamViewer 11 (or perhaps will in the next version 12) install process.

Hi,
Thank you for the solution. It took me a lot of time. The first time I forgot to change the MAC address and the temp files and it did not work. Later I changed the MAC address and followed every step and for now it seems to work. I will see after few days.
Leandro Andrade said…
worked perfectly in windows 10 and TeamViewer v11.0.66695. Thank You!!!
Rod Dines said…
@vinayv "Fix teamviewer commercial use suspected issue." Clarification: Procedure A in this post is specifically targetted at installing a "non-commercial edition" of TeamViewer on Windows Server installations. But as your link shows Procedure B (similar to the link you included) is also applicable to non-server clients that have been suspected of commercial use.

HS it worked! I was wracking my brain trying to figure this out..

and was hesitant to F with the MAC address.. but BAM!!

Thank you!
Aben Escalante said…
I couldn't get it to work, I followed the instructions, but it still says that it expired, I already change the MAC many times and deleted everything from the registry, I'm wondering if this workaround was fix on version 12.

and then wait...

@Gabriel Cersonsky
I think you will find this is a support request processes for free users having problems with the TeamViewer Personal Use Verification process and not a way to bypass the verification.
It says at the bottom in RED - "Personal usage of TeamViewer is not possible on a Windows Server operating system! This automatically qualifies as commercial use and requires a license."

Removing the WLAN / WiFi pcie card whitelist on Lenovo IdeaPad u410 Touch with BIOS update

WARNING! PLEASE READ THE ENTIRE POSTBEFORE USING / DOING ANYTHING!

BACKGROUND
I recently (early 2016) acquired a 2013 Lenovo IdeaPad u410 Touch.

It was not my first choice but still useful but I wanted to upgrade it to more recent tech and make it more usable as it is not the fastest CPU around, i.e. an i5-3337U dual core (quad thread) at 1.8GHz.
http://ark.intel.com/products/72055/Intel-Core-i5-3337U-Processor-3M-Cache-up-to-2_70-GHz


First thing I did was upgrade the BIOS to latest (as anyone would/should do really) version 65CN99WW (8/28/2014) available here:
http://support.lenovo.com/au/en/products/laptops-and-netbooks/ideapad-u-series-laptops/ideapad-u410?beta=false

I then added 2 x Kingston SO-DIMM KVR16LS11/8 1.35V (Low Voltage) 8G DDR3 1600 Notebook Ram SODIMM's despite the specs I could find all saying it would only take 8GB and it works fine with the 16GB as the Intel i5-3337U CPU (says 32GB) & Mobile Intel HM77 Express Chipset specifications suggest.

Migrating/cloning an Apple MAC OSX with Windows 7 / 8 / 10 Bootcamp partition to another hard or solid state (HDD / SSD) disk drive (Updated March 2018)

I got a Mac Book Pro 13" in 2012 that in 2016 I upgraded to a 240GB SSD from a similar sized 250GB HDD.  Since then I have followed this procedure a number of time for friends and customers. This week I again had to upgrade that same Mac Book Pro from the 240GB SSD to a new 480GB SSD and again came across a number of problems.  For this reason, I have decided to invest my time in documenting this troublesome process for the benefit of others and so next time I have to do it I won't have to remember and re-discover everything again.

TL;DR - The Crux of this article is that unfortunately, there is no easy way to just copy the whole old drive, with the different Mac and Windows Bootcamp partitions to a new drive. However, with this guide, the complex process is fully explained and broken up into five manageable and easy to understand processes along with their individual steps to do so.

NOTE: I use the word 'drive' loosely here but these processes could work to/or from eit…
