I was thinking about installing team viewer on the machine I got from my work, so that I can from time to time log in to my home machine when I want to do something on it while at work. I consider this being a personal use case, but I am not sure if it is the correct interpretation. I would be glad to find that out and be sure before I install it. What do you think?
Thanks for your question.
What you are describing is indeed a typical use case for commercial usage as it is a connection from your work computer.
The other way around: From your home computer to your work computer is also commercial. Basically every connection you make from or to your work computer requires a license.
If this is the only connection you want to make, I recommend the new Remote Acces license for you. I´ll get you the link for more information: https://www.teamviewer.com/en/content/lo-remote-access/
I hope this clarifies your question.
