Here is another alternative, to Craig's suggestions.

You can create a shared table with 100 (or 1000) records - the contents is irrelevant.

Create a lock for each user. Let's say you want a maximum of 10 users, in one particular installation.

MAX_USERS = 10
locate for rlock()
if recno() > MAX_USERS
  MessageBox("Buy more licenses.")
  cancel
endif
