The license for measuring with Dewesoft is included in the device (usually PROF version). Once it is connected to the USB port, it acts as a dongle.

The license for analyzing is free! Dewesoft can be installed on any computer and the stored data files can be opened, recalculated, and exported.

Additional licenses can be required for plugins, these can then also be written into the Dewesoft® device. To test plugins, you can request a 30-days-Evaluation license.


Under licensing section, you see your Active licenses, Create new license or Import offline license (*.lic file format).

Make sure that all the hardware which you intend to use is connected and switched on. Only in this case, the registration will be fully done for all measurement hardware being used. The license is then generated to hardware keys of the hardware OR to computer MAC address. So you can use the same hardware with the license file on any computer and you can also exchange the measurement hardware on the same computer with a need that MAC addresses are the same.

Offline registration

If your measurement PC has access to an internet connection you can register directly from inside Dewesoft software. If not Dewesoft will automatically offer offline registration.

Enter your license key and press arrow next to the license number button.


If there are no DAQ devices connected to the computer, the license is generated only for MAC addresses of the PC.


Dewesoft will connect to the internet and will register automatically (online). If there is no internet connection, Dewesoft will offer offline registration.


Dewesoft will create a *.lic file and you have to save it to the computer.


Copy the created license *.lic file from the measurement computer, and go to a computer with internet access. Visit Dewesoft home page, and select registration.

Drop the *.lic file to the window.


Restart Dewesoft software and select the option Import license. Import the *.lic file that was downloaded from the web page.

Write license to Dewesoft devices

When we have a license for software on our PC, we can also write the license to Dewesoft measurement devices. This can be done, so the devices can be used also with another computer.


If the license is already written on the measurement device, we get a warning. We can overwrite the existing license with a new one.


Write license to DS-DONGLE

NOTE: Only one DS-DONGLE will be recognized by DewesoftX software at the same time
