Troubleshooting APSIM Installations
For APSIM 7.10
International users running Microsoft Windows may have trouble with number & date formatting (eg commas vs decimal points in numeric entries), and may need to change their regional settings to Australian or similar.
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).
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:
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.
