I want to know whether the 32 or 64-bit version of MATLAB will be installed by default from the DVD. I would also like to know how to have the 32-bit version of MATLAB installed on my 64-bit Windows computer.
MATLAB: Which version (32 or 64-bit) is installed by default from the Windows DVD? How to install 32-bit MATLAB on the 64-bit Windows machine

Windows
MathWorks fully supports running 32-bit MATLAB on 64-bit Windows as of MATLAB R2010a. Even prior to R2010a this should still work, albeit with some limitations.
There are a handful of known issues with running 32-bit MATLAB on 64-bit Windows:
- MATLAB Parallel Server may fail when both 32-bit MATLAB and 64-bit MATLAB are installed on the same computer.
- Real-Time Windows Target will not run.
- Data Acquisition Toolbox cannot connect to parallel ports.
- Embedded IDE Link and Target Support Package may fail to start Code Composer Studio.
Similarly, cross-platform compilation is not supported: binaries compiled on a 32-bit system will only run in 32-bit mode, even on 64-bit operating systems. Binaries compiled on 64-bit operating systems will not run on 32-bit operating systems.
If you must run 32-bit R2009a or earlier on 64-bit Windows, be aware that you will encounter issues when invoking external C compilers and other third party applications. For this reason, MathWorks does not recommend running 32-bit R2009a or earlier on 64-bit Windows.
Lastly, MATLAB R2015b was the last release of MATLAB with a 32-bit version. MATLAB R2016a and later are 64-bit only.
Linux
To install 32-bit MATLAB on a 64-bit Linux machine, start the installer with the -glnx86 flag:
./install -glnx86The -glnx86 flag is also required when starting 32-bit MATLAB, and when using 32-bit network license manager scripts (lmstart, lmdown, lmstat, etc.).
Some users have problems loading the JRE when running in this configuration.
Creating a symbolic link named "glnxa64" in $MATLAB/sys/java/jre that points to "glnx86" should resolve this issue.
You can do this with the following command:
.ln -s $MATLAB/sys/java/jre/glnx86 $MATLAB/sys/java/jre/glnxa64MacOS
MacOS does not expose "bitness" to the user and will seamlessly run 32-bit and 64-bit applications side-by-side without issue on 64-bit systems. As of R2010b, MathWorks only builds a 64-bit version of MATLAB for MacOS.
The last release of MATLAB (and the Network License Manager) supported on the 32-bit Linux platform was R2012a. As a result, although you can use R2012a or earlier, versions of the License Manager created for R2012b or newer will not be usable on a 32-bit Linux Operating System.
If you would like to install a newer version of the Network License Manager, you will need to update accordingly.
The system requirements for the latest release of MATLAB (and the License Manager) can be located here:
Linux System Requirements – Current Release
It's also important to note that the version of the License Manager you are running will directly correlate to the version of MATLAB available on your license. For example, in order to run MATLAB R2013b you will need to be running the R2013b License Manager (or newer). An older License Manager will likely not work with the latest version of your license file.
