Can not get Stack Trace Decoder to load

I tried putting the damn EspExceptionDecoder.java in the appdata folder, the program files folder, and documents folder. It doesn't show up under tools. It was working before I upgraded to 1.8.8.

Any clues as to what might be wrong?

I see you've gone with the "shotgun" installation method, strewing files around your hard drive. The best way forward will be to delete all that and start with a fresh installation.

I'll provide instructions:

  1. Delete the folder at the following path:
    C:\Program Files (x86)\Arduino\tools\espExceptionDecoder
    
  2. Delete the folder at the following path:
    C:\Users\matt\My Documents\arduino\tools\EspExceptionDecoder
    
  3. Delete the folder at the following path:
    C:\Users\matt\My Documents\arduino\tools\EspExceptionDecoder.java
    
  4. Start Arduino IDE.
  5. Select File > Preferences from the Arduino IDE menus.
    The "Preferences" dialog will open.
  6. Take note of the path shown in the "Sketchbook location" field of the "Preferences" dialog.
  7. Click the "Cancel" button in the "Preferences" dialog.
  8. Select File > Quit from the Arduino IDE menus.
  9. Create a folder named tools under the folder at the path you noted from the "Sketchbook location" preference.
  10. Download the compiled latest release of the tool:
    https://github.com/me-no-dev/EspExceptionDecoder/releases/download/1.1.0/EspExceptionDecoder-1.1.0.zip
  11. Unzip the downloaded file.
  12. Copy the unzipped folder to the tools folder you created

The folder structure of a correct installation looks like this:

<sketchbook location>
|_tools
   |_EspExceptionDecoder
      |_tool
         |_EspExceptionDecoder.jar

Thank you. Now it loads.

You're welcome. I'm glad to hear it's working now. Enjoy!
