Too late for the OP, but here’s why I recommend against using TeamViewer.
I used TeamViewer for years to help my aged parents, because the company says it’s free for non-commercial use, which mine decidedly was.
Then last summer TeamViewer suddenly sent me a message saying they had detected that I was using it for commercial purposes (I wasn’t) and shut my account down unless I bought a license for (I think) $50 a month. I tried several times to appeal, or even get an explanation, but got no response at all from them. On Googling, I found that they had done the same to many people.
So you may find at some time in the future that you’re shut out of it unless you pay lots of money.
I have since switched to Remote Utilities, which I find quite satisfactory and is really free.
