Licensed users may access and modify all source code. All modifications to APSIM must be submitted to the AI and be subject to the Reference Panel evaluation process before inclusion into the official APSIM release. Instructions for Submitting Improvements to APSIM for Review by the APSIM Initiative Reference Panel can be found here.
It can be useful to notify the APSIM Initiative that you are planning on making an improvement to APSIM. This can often lead to others suggesting ideas or collaborators to work with.

Troubleshooting APSIM Installations
For APSIM 7.9
APSIM has been changed to use Microsoft Visual C++ 2015. The implications for users is that the installation process can be more complicated. The APSIM Installer will check for Microsoft Visual C++ 2015 and attempt to install it if required. On versions of Windows before Windows 10 (i.e. Windows 7, 8, and 8.1) it may be necessary for the user to manually install Microsot KB2999226 (Update for Universal C Runtime in Windows).
This update can be found here
For this to succeed though, it may be necessary to update Windows via Windows Update. For example on Windows 7, we have found it necessary to install Windows 7 service pack before installing the above update.
APSIM version 7.4 and 7.5 requires the following 2 Microsoft runtimes to be installed:
- The Microsoft .NET 4 Framework
- The Microsoft C++ Runtime for Visual Studio 2010
APSIM version 7.3 and earlier requires the following 2 Microsoft runtimes to be installed:
- The Microsoft .NET 2 Framework (included with the .NET 4 distribution above)
- The Microsoft C++ Runtime for Visual Studio 2008
The APSIM Installation should detect when the above two runtime libraries are missing and install them automatically. If this doesn't occur, then you can manually install them from the above links.
