Spectrum Software
Industrial Strength Simulation




Spectrum Software has released Micro-Cap 11, the eleventh generation of our SPICE circuit simulator.

For users of previous Micro-Cap versions, check out the new features available in the latest version. For those of you who are new to Micro-Cap, take our features tour to see what Micro-Cap has to offer.






We have a network license for multiple copies of Micro-Cap. The key is plugged into our Windows server, and the license manager has been installed. The clients can run Micro-Cap fine most of the time, but we intermittently run into problems where none of the clients seem to be able to find the license. I believe I have tracked down the trigger to this problem. When I installed the license manager, I did it through my administrative account on the server. Now it seems that whenever my account has been logged out or the server has been rebooted, none of the clients can access the license. I can fix the problem by just logging into my account again. Is there a way to get the license manager accessible to the client systems without having to login into my server account every time?


The license manager can be installed as either an application or as a service. If it is installed as an application, then its availability is dependent on the user whose account it was installed into being logged into the server. If that user is not logged in, then the application will not be running.

The way to get around this is to install the license manager as a service. For Windows servers, the LMSetup.exe executable file provides the option to install either as an application or a service during the basic install procedure. During the LMSetup installation, one of the screens should state:

Do you want to install HASP License Manager as an application or as a service?

Service is the recommended option for installation. When installed as a service, the license manager software will always be running whenever the server is on. It does not matter if any user is logged in or not.
