Often times we get customers that call in confused about how to read the license counts shown in the SolidNetWork license manager; i'm gonna try and clarify how this works because it can get confusing...
On the license manager you'll find a tab called "License Usage"; here you'll see a drop down where you can select from each of the different types of licenses you've purchased.
The confusion comes in when you look at the SolidWorks Standard; if you have a package of SolidWorks above Standard, i.e. Professional or Premium, the license manager is going to show more Standard licenses then you actually have. This doesn't mean you've magically gained more seats of SolidWorks. The best way to think about it is the total number of Standard licenses shown on the license manager is the total number of SolidWorks seats you've purchased. For example, if you've purchased 1 Standard, 1 Professional, and 1 Premium license, the license manager will show you have 3 Standard licenses available. The reason for this is the license manager is set up in a way that when you access a Professional or Premium feature within SolidWorks, that license is pulled from the license manager; however, you still have access to Standard features as well so therefore need a Standard license. Back to our example, this is where the 3 available Standard license come in. Say you start up SolidWorks with only Standard features enabled; one of those Standard license from the license manager will be pulled. You then turn on a Premium feature and the Premium license is then pulled as well, but you still have the Standard out. At any one time the most licenses that could be used in this example would be 1 Standard, 1 Professional, and 1 Premium.
When it comes to network Simulation Professional, Premium, or any other Add-On licenses, these are just add-ons to the basic packages of SolidWorks so when the add-on is turned on in SolidWorks this license is pulled. It does matter what SolidWorks package is in use (Standard, Pro, or Premium).
Hopefully that clears up some of the confusion when it comes to reading you license count on the SolidNetWork License Manager.
