So all the java softwares currently not working?

Hey, I was using a portable Java launcher to play Minecraft and other games off my USB drive. It was working for a bit until just recently it started giving me an error message saying that it cant run and needs to be reinstalled. Just wondering if this was because I deleted the files for Java (not the launcher version) Or if there was some sort of update that needs to be worked on. If it's because I deleted the files for Java, is it possible someone can give me an outdated version of Java for the time being because it seems it has been updated, and it seems to not be compatible with the launcher. PS I did reinstall the app however it didn't fix the issue.
