I am trying to install and use Salesforce Data Loader (v67) on my Windows machine. I have successfully downloaded the latest version, extracted the files, and completed the installation process. However, when I try to open Data Loader, the application does not launch properly — a terminal window briefly appears and immediately closes, and the GUI never opens. I have also tried doing a completely fresh installation by removing all previously installed files and configuration data, but the issue persists. Could someone please help me resolve this?

Hi Anish,
That blink is the launcher hitting an error and the console closing before you can read it. On Windows, Data Loader starts from a batch file, so a double-click gives you a window that vanishes the moment Java fails.
Open Command Prompt, cd into the folder you extracted, and run dataloader.bat from there. If you installed with install.bat, run that the same way so the text stays on screen. Whatever line it stops on is the real failure. Wiping the old config won't show you that line.
Current Data Loader does not bundle Java. Salesforce's install notes say to install a Java 17 runtime first, 64-bit. Azul Zulu 17 is the one those notes point people at. Set JAVA_HOME to that JDK folder, put its bin directory first on PATH, then open a new Command Prompt. Run java -version in that window. If it isn't the Zulu 17 you just installed, the bat file is still seeing a different Java, or none.
The other thing that causes the same blink is the folder. Extract to a short path such as C:\DataLoader. Skip Program Files, OneDrive, and any path with spaces or non-English characters. If Windows blocked the zip, unblock it and extract again.
Config for a given version lives under your user folder in dataloader, then the version, then configs. Clearing that is fine, and it still won't open the GUI if JAVA_HOME is wrong. The write-up is Install Data Loader and Considerations for Installing Data Loader.
