2. Remove old versions
MCAS-S should be able to run version 4 with older versions such as 3.2 already installed. However you can only have one instance of MCAS-S 4. If you are having trouble running the installer, try completely removing MCAS-S from your machine.
To remove MCAS-S: go to Control Panel, Programs and features, find Multi-Criteria Analysis Shell, right click: Uninstall. Ensure that the software folder is removed from Program Files (x86) and that the icon is removed from the desktop.
3. Run the installer
Double-click the MCAS.msi installer and follow the installation instructions. Install the software on a local hard drive. The default location is C:\Program Files\ABARES\Multi-Criteria Analysis Shell vX. If this doesn't work see step 2 above.
4. Get MCAS-S ready data
To start using MCAS-S you need a project saved alongside MCAS-S ready data. If you don’t have your own data get started with some of ours.
- Download the sample project and data 'Where to live in Australia' [zip 190 MB]. You can follow the steps in the user guide using this project. Save the sample project in your workspace - just make sure you take the whole folder as the data and project need to stay together.
