Hi @jbaxter7,

The issue appears to be related to your Java version. According to the log, you're using version 8, but IFS Developer Studio 18 requires JDK 11 or higher. It officially supports JDK 11, 17, and 20. Could you try updating your Java version and run it again? And please let us know the outcome.

Best Regards,

I’ve tried using Open JDK 11 and that didn’t work either. I also have a coworker that only has JDK 8 installed but it worked for him.

From my understanding looks like the installer installs OpenJDK 11.0.11, and is using that to run since in the log file java.home is set to C:\Users\e302528\AppData\Local\Temp\NBI58890.tmp\_jvm and the first value for java.library.path in the log file is C:\Users\e302528\AppData\Local\Temp\NBI58890.tmp\_jvm\bin, which is the JDK that the installer created. When I go to C:\Users\e302528\AppData\Local\Temp\NBI58890.tmp\_jvm\bin in command prompt and run the command “java --version”,  it prints out Open JDK 11.0.11 which is also printed out in the log file. Since looks like the installer is installing this JDK and using it to run, I have no idea why it’s not working.

We have made a new release of IFS Developer Studio 18 tool a two days ago. Could you please download it and try out?

I downloaded it but still got the same error when running it.

I got the installer to work.

As crazy as it sounds, the reason the installer was failing was because I had a shortcut on my desktop that was pointing to something that no longer existed. I basically figured it out by creating java code for a GUI that allows you to choose a location on the file system since from the stack trace in the log for the installer I realized that's what the installer was doing. When I created the code in eclipse, I set it up to use Open JDK 11 since that’s the JDK that the installer uses.

This is the code I used to replicate the error:
 

import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JFileChooser;
import java.io.File;
public class MyDialog extends JDialog  {

    public MyDialog(){
        super(new JFrame("prova"));
    }

    
    void selectRoot() {
        JFileChooser ch = new JFileChooser();
        ch.showOpenDialog(this);
        File directory = new File("C:\\Users\\e302528\\Documents\\NMRO\\Software\\IFSDeveloperStudio");
        ch.setCurrentDirectory(directory);
    }
     

    public static void main(String�] args) throws Exception{
        MyDialog myDialog = new MyDialog();
        myDialog.show(true);
        myDialog.selectRoot();
    }
}

When I ran the code I was able to get the same exact error as the installer, and I put a break point at the call to Arrays.sort at line 317 in Win32ShellFolderManager2.class code (from the installer stack trace, I knew it was failing somewhere in Win32ShellFolderManager2) so that I could grab a list of file paths on my machine from the secondLevelFolders variable when I ran my code in debug mode:

I realized that the  majority of the file paths were paths to desktop shortcuts, and I deleted the shortcuts one by one until the installer worked. It worked right after I deleted a desktop shortcut that pointed to something that no longer exists.
