When trying to install Matlab 2020b getting error "The installer could not start the JVM"

I am working to deploy MATLAB R2020b using PSAppDeployToolkit. I downloaded the installer from Mathworks, unpacked it using the wizard to download the installation files, and manipulated my script for 2020a. When I first start the script, I get the error:

The installer could not start the JVM.

Could not find file C:\users\<user>\<path>\sys\java\jre\win64\jre/bin/server/jvm.dll

When I browse to that location in the package, the dll is present. I tried updating Java and installing the JDK to no avail. Any ideas?

I found the issue was that during my pre-installation step, I used a block of code to check for previous installations of MATLAB and then I used what I thought was a generic uninstaller from the application's directory. It turns out that the installers are probably unique to each version and a single uninstaller cannot be used to uninstall each different version of MATLAB. Once I referenced each version's unique uninstaller, the error went away.

Hi,

This problem occurs when running the installer from a folder that has a space anywhere in the directory path. Because of this, running the installer from a folder on the desktop on a typical Windows XP machine will fail because the "desktop" folder is contained within the "Documents and Settings" folder.

To work around this issue, create a new folder on the C: drive that has no spaces in the name and move the downloaded files into this new folder.

Execute the installer from there and it should run successfully.
