How can I compile standalon app with x64 MATLAB and Compiler for x86 cpu?

I would like to compile a standalopne application. I have x64 MATLAB and Compiler but I'll use the standalone on a x86 PC. Is there any option to define the target cpu?

From the mcc documentation :

 -win32 Run in 32-Bit Mode

Use this option to build a 32-bit application on a 64-bit system only when the following are both true:

    You use the same MATLAB installation root (matlabroot) for both 32-bit and 64-bit versions of MATLAB.

    You are running from a Windows command line (not a MATLAB command line).

Is that mean I have to install a 32-bit MATLAB as well? Because I have tried it but it said "Unable to find suitable install area".

Yes you also need to install 32-bit MATLAB.

You can install both 32 bit MATLAB and 64 bit MATLAB on your computer. Use the 32 bit MATLAB to compile an app for a 32 bit operating system, and use the 64 bit MATLAB to compile an app for a 64 bit operating system.

But if I want to deploy a universal standalon app what can run on x86 and x64 too, is that enough to deploy it with 32-bit MATLAB? So can a 32bit standalone run on a x64 PC?

Yes it can - a 32 bit app can run on a 64 bit computer. Those are all the programs you see in the Program Files (x86) folder. But of course the converse is not true. A 64 bit app can't run on a 32 bit computer.
