Did you execute the command with the double quotes (")? They should not be necessary and could cause a problem.
Was there any command output?
If the computer shuts off this is likely a problem with the computer, not with portmapper. Can you try it on another computer?

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Hi!
You need Java 11 or later. Then you download the portmapper jar file and either double click it or execute the following on the command line:
java -jar portmapper.jar
You can find detailed instructions on https://github.com/kaklakariada/portmapper#readme
Hope that helps!
Thanks for responding. I had java ver 8 and uninstalled it and installed "jdk-11.0.13_windows-x64_bin"
I executed this at the command line and the computer shut off. java.exe" -jar portmapper.jar
I've read the github page.
