Downloading Vensim

You can download Vensim from our website http://www.vensim.com.  Your purchase of a Vensim license includes one year of free electronic updates, thereafter you will need to pay the maintenance subscription fee to receive updates and technical support.  You can check our website to see what versions are available.  The menu item Help>Newer Released will also tell you if a more recent version is available.

The direct link for downloading Vensim is http://www.vensim.com/download.html.  When you use the link for licensed software you will be asked to enter your registration code (see below).  The registration code identifies the product you have as well the date through which you have continued maintenance.  To download the Model Reader or Vensim PLE for educational use go to http://www.vensim.com/freedownload.html.

Once you enter your registration code you will be able to choose between the versions of Vensim available to you.  You should choose the most recent available version unless there is a specific version you need.

Windows:  The Windows installer files have names that depend on the product (for example, vendss32.exe for Vensim DSS).

The installation program will work whether you are logged on as an administrator or standard user. If you are logged on as a standard user installation will be to local folders.

Macintosh: There are separate installers for the program and documentation on the Macintosh (the documentation includes the sample models and function examples).  The program installer is specific to the product configuration while models and documentation are common.
