The Conda-based installation procedure for Osdag is valid across platforms, which include Windows and Linux distributions.

1. Install miniconda3 (docs.anaconda.com/miniconda/install) if not installed already. If it is already installed, please update to Miniconda3 v25.11.1. Any other installation giving access to the latest conda version (e.g. Anaconda, miniforge, etc.) is also OK.
2. Open the conda-enabled shell. (Instructions are available on the Miniconda3 installations page)
   1. a. For Windows: Open the Anaconda Command Prompt or Anaconda PowerShell Prompt. These should be available from the Start menu after installation.
   2. b. For Linux: Open the terminal.
3. Run this command:

   conda create -n osdag-env osdag::osdag -c conda-forge

   This will create a new environment and install Osdag in it. It may take several minutes to get the prompt back.
4. To run Osdag, from the same shell, run these two commands:

   conda activate osdag-env

   osdag

5. This will open the Osdag application.
6. Attempt a sample problem to make sure everything is working.
7. To run Osdag in the future, follow Step 4. This will not require an internet connection.

Updating Osdag

Note: These instructions will be applicable only to prospective releases. For any previous version before v2026.02.0.0, these commands will not work.

U1.	Occasionally, update Osdag as new updates may have been added since the install. You should check the release notes of the updated version for any further instructions.
U2.	To update Osdag, run these two commands: conda activate osdag-env conda update osdag
U3.	To open Osdag after updating, run this command (with osdag-env activated): osdag
U4.	To run Osdag in the future, follow Step 4 from the installation instructions. This will not require an internet connection.

In Case of Issues

1. A. In case of issues during Steps 3 or 4, i.e. if Osdag is not installed or does not run, you could try to use the alternative mamba solver.

   A1.	To activate the environment, run: conda activate osdag-env
   A2.	Run this command to install mamba: conda install mamba
   A3.	Run this command to install Osdag through mamba: mamba install osdag::osdag -c conda-forge -c osdag

2. B. In case you already have an older version of miniconda3, update it to the latest version.

   B1.	Run this command to update miniconda3 to the latest version (v25.11.1): conda update conda
   B2.	Check if miniconda3 has been updated to the latest version conda --version
   B3.	This should show that it has been updated to v25.11.1 in the terminal. If updating does not work, uninstall miniconda3 and reinstall it (follow the installation instructions after uninstallation of the older version).

Minor crashes may happen in Linux systems. Refer to this webpage (https://github.com/osdag-admin/Osdag/issues) to explore known issues and their possible solutions. This version of Osdag is not compatible with macOS.
