I carry out personalized management programs. I usually install the programs, and over time I make updates that clients ask me for. As well as to install demo programs, and waiting for the client to decide or not to purchase it. I don't go online much, sometimes 3/4 times a week. 2 days ago I installed the free version, to test it, and before I used Teamviewer, but a friend recommended yours to me. And sometimes I install the programs on the client's server, and then I put direct access from the application to the server on each computer. Which version is the one that you advise me?
