Before being able to run any simulations with nextnano, you need a valid license.
If you haven't purchased one yet, please contact us - you can for instance use the Need help
button in the right lower corner.
For each PC where you want to use nextnano, you have to activate your license(s). For the online activation, you need an internet connection.
If you are using the nextnanomat for the first time, the license activation window will pop up automatically. If not, use Tools
→ Activate License
from the main menu.
This form should pop up:
/* It is important that you specify your email address correctly because we have issued your license to a specific email address. This is a comment! /*
The destination to save your licenses is set automatically to a folder “License” in the same directory as nextnanomat.exe. If you are running nextnanomat in your program files or another directory with no write access (i.e. read only access), we recommend to specify a custom destination for your license file(s).
After filling out the dialog, press Generate and activate license key
.
Important, use the same email address which was used to purchase the license(s).
You can see the status of the activation process in a small window. (If an error occurs, it would be helpful to send us a screenshot of this dialog. Then we can identify the error quickly.) If successful, it should look like this:
Afterwards you just need to update the paths to your newly activated license(s). If you click yes
, the nextnanomat progam is taking care of this automatically.
Alternatively, you have to manually update the paths to your new license(s) under Tools
→ Options
.
Note that the license file for both nextnano++ and nextnano³ is called License_nnp.lic
. (license.txt
is the previous format.)
Congratulations, you can now start your actual simulations!

ClientSideActivator.exe
has to be located next to nextnanomat.exe
. You can either search for it manually, or just redo the operation after putting it in the correct place.
After clicking the “Generate and activate license key” of the activation dialog
ClientSideServerActivation.exe
must be located in the same folder as nextnanomat.exe
. You can either search for it manually or put it in the correct location and restart the activation process. If you don't find this executable at all, you can use the offline activation and send us the generated fingerprint file per email - we will do the license activation for you and send you the license file by email.
In any case please notify us about occurring problems - we are always trying to improve the licensing process to make it as convenient as possible.
If no connection to the server could be established, you can tick the offline activation in the activation dialog.
Generate and save the fingerprint file to any convenient location and send it to us per email or any other support channel.
We will generate your license and send it to you.
You can do online (recommended) or offline activation using the Command Prompt.

In the older version of nextnano there will be an error Error: Wrong number of arguments
which can be ignored as long as the fingerprint file user_fingerprint.txt
has been generated. (Please also get an update of nextnano.)
Finally, the generated fingerprint file user_fingerprint.txt
which contains your
has to be sent to support@nextnano.com. We will then send you your license key within 24 hours.
