If you purchase multiple licenses, then its easy to lose track of which machines they are assigned to.
The License Viewer allows you to keep track of the licenses you have activated.
To access it
- Select the Help->About Menu
- Click 'View Allocated Licenses...'
Each activated machine may have several entries, one for the version of the product you bought, the other for Upgrade protection (if you purchased it).
You can only view the distribution of licenses that are already installed on this machine, ie if you have no licenses installed you will not see any entries.
