Our software packages can be delivered with several types of license, depending on what is best for our customers. This section describes the different choices.
The license is activated for a specific PC and a specific user. No dongle is needed. No internet connection is needed after
installation. Multiple instances of the software can be started by the user.
During the activation procedure our software generates a so-called activation file which contains specific information about the computer and the user. Based on this information the license allows the software to run on this computer and for this user only.
If the computer crashes or you want to use the software on a new machine for some other reason, we need a legal document signed by officials of your organization to confirm that the original computer is not used to run the software any more. We can provide a template for this document on request.
Single instance license
The license is activated for a specific PC but not for a specific user. No dongle is needed. No internet connection is needed
after installation. Only a single instance of the software can be started.
This type of license is made for spectrum analysis
after data acquisition with a spectrometer system. In such a case there are often various potential users who want to log-on with their own user account.
The license can be used on several PCs by several users. No dongle is needed, but a permanent internet connection is required.
The use of the license is managed by our license server. When a user works with the software the license is blocked for other users. The license is re-newed after short time intervals (some minutes). When the user finishes the license becomes free for other users after a few minutes.
A user can decide to check-out a managed license for offline use. In this case the license becomes an activated license for a limited time, typically over the weekend or during travelling without internet connection. During this period of time the license is blocked for other users.
In some cases we still deliver dongle licenses which require a USB software protection key to be active at one of the USB ports of the computer. Dongles must be purchased at extra costs which depend on our expenses for the dongle itself and shipping costs.
