Install Adobe DC Team

I just purchased Adobe DC Team (7 Licenses)... I am the administrator on all my machines. So I need to download and install on them under the admin account. When I assign users, it wants me to put the user e-mail account in. I don't want that going to my users. So when I tried to use my e-mail, I can only use it once. The bigger problem is that I personally have 3 of the machines so I cannot assign the other two licenses to them because I used my license on the initial one. Huge dilemma. Can anyone assist... Thanks...
