Hi,
The process status application programming interface (PSAPI) is a helper library that makes it easier for you to obtain information about processes and device drivers.
This error occurs when MATLAB fails to resolve the dependencies of libmwbuiltins.dll and as a result it throws the error psapi.dll is missing or is out of date.
1. Go to C:\Windows\system32 or system64 folder and locate psapi.dll.
2. Right click on the file and select "Properties."
3. Go to the Version tab and check what version of the .dll file is installed.
If the file version is old, it means that .dll file is out of date and thus to resolve the issue you will have to install matlab again and only then you will be able to launch it.
I hope this helps.
