System Requirements

Installing Anaqsim

Anaqsim can be downloaded from the website.  The downloaded file is a Windows Installer package (.msi) file. To start the installer, run or double-click on the  downloaded file.  The installer guides you through a typical installation process. The installer also checks to see if the right version of the Microsoft .net runtime libraries are installed on your computer (these are used  by .net programs like Anaqsim).  If they are not there, they will be downloaded (free) from a Microsoft web site and installed before Anaqsim is installed.

Once installed, the program will be included in the Programs part of your Start Menu.  Anaqsim is typically installed in the following directory on your hard drive: 
Program Files/Yellow Sub Hydro/Anaqsim.

Anaqsim control files (with extension .anaq) are not automatically associated with the Anaqsim.exe executable.  In order to assign an association which enables Anaqsim to open automatically when double clicking on a .anaq file, the following process needs to be undertaken:

  1. Right-click on an existing .anaq file (for example one of the tutorial files, found under the 'Documentation' folder)
  2. Select 'Open with', and then 'Choose another App'
  3. Scroll down to 'Choose an App on your PC'
  4. Navigate to where you installed Anaqsim (typically Program Files/Yellow Sub Hydro/Anaqsim) and select the anaqsim.exe file
  5. Select 'Always' to ensure that the file extension association is saved, and applied to all .anaq files.

When you first start Anaqsim it is unlicensed;  it will run but will have constraints when solving the system of equations, and a watermark when plotting outputs.  Activating a 'Quick Designer' license will remove the watermark, and activating a 'Deep Designer' license will additionally lift the model solve constraints.  If you have purchased activations, see License Menu/Activating a License for instructions on how to activate your license.

Licensing Anaqsim

Anaqsim by default installs in 'Demo' mode which has limited capabilities and is not for commercial use.

The implementation of licenses has been changed from December 2023. Anaqsim version 2023-2-0 or later will be required to check a license key activation status of a license purchased after December 2023.

You may purchase time-limited licenses for Anaqsim, which increase its capabilities.  Anaqsim licenses are locked to a specific computer for a specific time period (from December 2023, 1 year from purchase; prior to December 2023, 1 year from activation). 

The following process is required for activating a licence:

  1. Make sure your computer is connected to the internet (required).
  2. Select 'License'/'Activate License on this Computer'.  
  3. When prompted, enter your activation key code (sent via email to the purchaser at the time of the purchase) and press OK.  
  4. Anaqsim will activate a license on your computer.  When an activation expires, purchase a new license or, if multiple activations purchased prior to December 2023, use another activation to add another year of Anaqsim use.
  5. Check that the license is functioning correctly by selecting 'License'/'License Status this Computer'.  The license expiration date will be printed to the run log.

For licenses purchased after December 2023 – Each activation key contains a single activation.  If you have purchased multiple licenses, you will receive multiple activation keys.  Each key is valid on one computer for 1 year from the date of purchase. The type of license and expiry date will be printed to the screen.

For licenses purchased prior to December 2023 – Each activation key may contain one or more activations.   Each activation is valid on one computer for 1 year from the time of activation, and there is no time limit for initialising activations. The number of activations initially purchased, the number of activations used so far and the number of activations still available will be printed to the screen.

Upgrading licenses

If you wish to upgrade from a 'Quick Designer' to a 'Deep Designer' license whilst your 'Quick Designer' license is still active you will receive an error message when you attempt to activate your new licenses saying that the computer is already licensed.  This is to prevent you accidently overwriting an existing license if you were not aware that the computer was already licensed.  The following steps need to be followed:
   1.   Delete the anaqsim.licn file found "C:\ProgramData\AnAqSim"
   2.   Activate your new 'Deep Designer' license as per the instructions above
