I downloaded the tracer viewer and tried to start it at my Windows 11 VM (not using vdi just a regular vm)

It starts each time, I have tried using jdk 11, 21, & 24

Here is info from when I use jdk 21

Hi BhumiReddy, I did download from here. I couldn’t see error, but just opens and closes

re: it just opens and closes.

I think you should try running it from the command line, this way you should be able to see any error(s). I downloaded it, extracted to the temp folder, and than ran the command from the command line in windows 11:

C:\temp\pega-tracerviewer-3.4.3\pega-tracerviewer-3.4.3\bin>pega-tracerviewer.bat
