When I try to open Moppy 2.10 it opens a file that looks like a terminal, and then it closes it after a second.

Probably a JAVA_HOME or Java versioning issue. You can check the log file (somewhere near the .bat file you're opening), or you can run the .bat file from the command line instead (Open up the command prompt first and then type the name of the .bat file) to see the error.

You'll need to have JAVA_HOME set properly, and have at least Java 12.

I says it is not a internal or external .bat file that it can open

Here is more precisely what is says:
'This' is not recognized as an internal or external command,
operable program or batch file.
