Prerequisite on Redistributable Not Detecting Key

I am currently making a package that has Matlab Runtime as the prerequisite.

My prerequisite has a condition that checks if key exists (HKEY_LOCAL_MACHINE\SOFTWARE\MathWorks\MATLAB Runtime\9.3) and prompts user to install if the specified key does not exist.

However, when I run the setup.exe, it still prompts me to install the MATLAB Runtime even though I have installed it and have the key listed in my Registry Editor.

Here is the output of the debuglog:

How to make Installshield detect the prerequisite properly?

Hi Pyrena,

Check where is prereq looking for MATLAB Runtime-Keys.

Is it the win64 or win32 part of registry hive ?

Find out where MATLAB Runtime put the registry key ( 32 or 64)?
