# nextnanomat on Linux¶

We strongly recommend using |nextnano| on Windows.

nextnanomat is programmed in C#, and can thus be executed on any operating system. It is, however, developed on and optimized for Windows. On Linux, you have to either install Wine or Mono and then execute nextnanomat.

Please note that we developed nextnanomat for Windows and not for Linux, therefore many things might not work as expected.

Status 2020-04-07: Recommended to use Wine as described below.

Status 2018-05-03: Recommended to use Wine as described below.

## Option 1: Wine¶

The following instructions are for Ubuntu version 20.10 (Groovy Gorilla). Commands for the Wine installation on various distributions are given in Wine Installation. A detailed description on how to install WineHQ on Ubuntu can be found here: Install WineHQ package on Ubuntu

The following commands are needed to install WineHQ on Ubuntu 20.10 (Groovy Gorilla). For older versions of Ubuntu, please see here: Wine Installation

sudo dpkg --add-architecture i386
wget -nc https://dl.winehq.org/wine-builds/winehq.key
sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ groovy main'
sudo apt update
sudo apt install --install-recommends winehq-stable


• Unzip this file.

• Open a Terminal window and change to the directory where the nextnanomat.exe is located.

• Type: wine nextnanomat.exe

• There will be a pop-up message that a Mono package is missing which can be installed automatically. Click ‘’Install’’.

• There will be a pop-up message that a Gecko package is missing which can be installed automatically. Click ‘’Install’’.

• If nextnanomat does not work, close the terminal and open a new terminal and then try again.

The first thing you have to do when nextnanomat opens is to activate your license using:

$wine ClientSideServerActivation.exe -O ~/Documents -UF "Homer" -UL "Simpson" -UE "homer.simpson@nextnano.com" -E "homer.simpson@nextnano.com-2021-12-31-l1s4" -In "Springfield Nuclear Power Plant" -A "license.nextnano.cloud" -Exe ClientSideActivator.exe  You obviously have to replace homer.simpson@nextnano.com-2021-12-31-l1s4 with your name and your License key. If everything works, you will find the license file License_nnp.lic in your home directory. If it does not work, use Offline Activation: $ wine ClientSideActivator.exe -O user_fingerprint.txt -UF Homer -UL Simpson -UE homer.simpson@nextnano.com -In "Springfield Nuclear Power Plant" -E homer.simpson@nextnano.com-2020-05-12-dt34


Then the generated fingerprint file user_fingerprint.txt which contains your

• Computer Name

• Disk Hash

• CPU Hash

has to be sent to support [at] nextnano.com. We will then send you your license key within 24 hours.

Please note that we developed nextnanomat for Windows and not for Linux, therefore some things might not work as expected. Optionally, one can execute the nextnano++ and nextnano³ executables on Linux using Wine without nextnano. You have to type in: ... (Add an example here…)

Known problems are:

• On very old CPUs, the 64-bit version of nextnano++ does not work. In this case, please select the 32-bit version of nextnano++. Tools => Options => Simulation => nextnano++ executable => <path>\nextnano++\bin 32bit\nextnano++_Microsoft_32bit_serial.exe

• Somehow the settings are not saved, i.e. each time one starts nextnanomat, the license has to be activated anew.

• The program crashes.

Things that have to be fixed for future updates are:

• Use a monospaced font for the Input tab. (It seems that the default font for Windows is not found and then another default font (Tahoma) which is not monospaced is chosen.) One can choose a different font for the editor. Tools => Options => Editor => Editor font

The following instructions are for Ubuntu version 18.04 LTS.

Run commands in a terminal:

sudo apt update      # Update system

sudo apt install wine-stable winetricks # Install required packages (without "-stable" in versions bevore Ubuntu 16.10)

winetricks dotnet45  # Install .net support, follow along on-screen instructions, ignore warnings

winetricks corefonts # Install basic fonts of Windows


Finally run winecfg -> Select “Windows 8” in Applications -> Windows Version and reboot afterwards.

To start the application, use wine /<your_directory_name>/nextnanomat.exe

Example: ‘’wine ‘/home/ubuntu/nextnanoTestversion/nextnanomat.exe’ ‘’

## Option 2: Mono¶

(This documentation should be updated for the latest Ubuntu and Mono versions.) It is not clear if it still works!

mono nextnanomat.exe &


On some Linux distributions (e.g. Ubuntu), Mono is already preinstalled.

The current Mono version uses .NET Framework version 4.0 by default. nextnanomat, however, still requires the installation of the .NET Framework version 2.0. Therefore the following error occurs:

The assembly mscorlib.dll was not found or could not be loaded.
It should have been installed in the /usr/lib/mono/2.0/mscorlib.dll' directory.


The following solution works:

sudo apt-get install libmono-corlib2.0-cil
sudo apt-get install libmono-winforms2.0-cil
sudo apt-get install mono-complete


All nextnanomat features seem to work on Linux Ubuntu. However, what does not work satisfactorily is the coloring of the 2D plots. They look too bright, so one can hardly recognize the results. A quick fix is to activate “Show grid”. Then the figure looks better.

If you have any feedback on these instructions, please let us know, then we can keep our documentation up to date.

We can also provide a command line version of nextnano for the various Linux distributions on request.

You can contact us at support [at] nextnano.com`.
