This is the number of actual users or machines (whichever number is greater) where this tool will be installed. To be compliant with our licensing, each physical user requires an End User License. Each user license is also entitled to (tied to) technical support.
If this is a shared machine with 1 shared account, and 3 users sharing the machine, you are required to have 3 end user licenses allocated to each user (as they will be using this tool).

This is NOT the number of SharePoint clients or end users using the SharePoint site.

For Example:
If you have 5 Site Owners who need to scan their sites for Permission Reports, and the tool will be installed on each of their desktops, "No. of Users (who will use this product)" value would be 5.

If you have 1 SharePoint Administrator who needs to scan sites for Broken Link Reports, and the tool will be installed on 3 machines (for example: to offload resources), "No. of Users (who will use this product)" value would be 3.

If you have the tool installed on 1 machine, using a service account with 5 users sharing it, "No. of Users (who will use this product)" value would be 5.

The SharePoint Essentials Toolkit license model is 'per seat' or 'per named user'. If you have 100+ Users who require licenses, we also offer a 'concurrent user' license model.
