So if I use the portable viewer and the "agent" for spontaneous remote support sessions it will count against the 10 key license...
The rule of thumb is - in your Viewer you can have as many connection records (entries in the address book) as your license permits regardless of whether it's portable or installable Viewer. In case of the free license it's 10 records.
Take a look at this picture https://www.remoteutilities.com/images/help/ab-components.png
. It explains what a connection record is. Normally, each address book record corresponds to one remote PC, although you can also create multiple records for the same remote PC.
In other words I have only 10 sessions available to me to make spontaneous remote support connection with the 10 key license ...
Not exactly. I think I need to give you an example:
Suppose you have a physical address book with names and phone numbers of different people. You can call these people and chat with them at any time without any limitations.
However, your address book can only hold 10 records. In order to add one more record to that address book you need to remove one of the existing records to make available space.
It doesn't really matter whether you spontaneously call those people (think "Agent") or call them on a regular basis (think "Host"). Also, it doesn't matter whether you call them all at once or one at a time - the only thing that matters is how many records your address book can hold. If you no longer contact a certain person, you can remove their record and add a new one instead.
Hope that helps. :)
