I wanted to add this for others who may find themselves here. If you're like me and many others who help their less tech-savvy friends and family, then TeamViewer Host may be your solution. It was developed for use on unattended computers, such as server interfaces and inherently does not need to be updated often. It cannot create outgoing connections, but that should be fine when used for the support recipient. The best part is it requires zero interaction from the recipient. No IDs or passwords have to be given, you can access an older version with newer versions, and I believe you can even remotely update the TeamViewer Host, if I recall correctly. This will require some trust from both parties, though, as you can technically access their computer at anytime. All of this comes with the free version, too. I do not own a purchased license, and I use this method. Hope this helps..
