Downloading the paid version

The latest download link(s) are provided to the customer in the order confirmation email. The updated link is also found below. Via this link, you will find all downloadable versions on the server, and their corresponding file checksums.

The organizational version is separate from the free consumer installation package. The free version must not be chosen for installation if you have an L'Math license code, as you will miss all the paid features and the license statistics will be missing.

Want to automate it?

The installation bundle path will always be the same:

Notes on different operating systems

Windows

  •  Windows installer based on Inno Setup as an exe file
  • Automated installation can be done i.e. with Intune, and manual installation is also possible using the installer GUI
  • Docs for the CLI params can be found in the
    Inno Setup docs
  • Starting from version 1.10.11, the installer packages are digitally signed with an Azure Trusted Signing certificate

Example: Silent installation

Esimerkki hiljaisesta kaikille käyttäjille tehtävistä asennuksesta (järjestelmänvalvojan oikeuksilla), joka ei sammuta L'Math-sovellusta, ja kirjoittaa lokin tiedostoon lmath_install.log :

setup.exe /SILENT /VERYSILENT /ALLUSERS /NOCLOSEAPPLICATIONS /LOG="lmath_install.log"

MacOS

  • For Mac, a DMG image is published, with the L'Math app bundle and a folder link to Applications
  • There are varying installation methods, the DMG image is mainly meant for manual installation – Mac experts will know more about automated installation.

GNU/Linux

  • For Linux, both AppImage and deb files are published
  • Installing is as easy as copying the AppImage to a known location and adding shortcuts and/or .desktop entries to the user
  • The .deb installation package will manage icons and file associations automatically

Installation script

With the provided script the newest L'Math paid version can be downloaded and installed automatically to a GNU/Linux device. The script will download the most recent AppImage file, place it under ~/.lmaths and install the required .desktop entries for the user. Feel free to open the link and modify the script to your needs, or see the script's help with the flag
--help.

Below are some example usage cases for downloading and running the script in a typical GNU/Linux system. Please note that the script can also be used for automatically updating the AppImage. The -y flag will silence the script's confirmations, and just install.

Älä koskaan kopioi ja aja verkosta komentoja, joiden tarkoitusta et tiedä.
Suosittelemme lataamaan kyseisen skriptin ja tutkailemaan tai muokkaamaan sitä tarpeisiinne sopivaksi.
