I wouldn't worry about it. What it means when it says it can harm your computer, is that if the program was written by a malicious person, it could contain malware. I trust OpenMotor and don't think I've ever heard of anyone getting malware from it yet.

If I remember correctly, JDK stands for Java Development Kit. Make sure you find the right version for your operating system, but it should be free and easy to install.

openMotor creator here. I think you might be talking about OpenRocket, because it is a Java program and requires a JDK (Java Developer Kit). openMotor is provided as a native executable and doesn't require anything else to run.

OpenRocket is for simulating rocket flight, while openMotor simulates when happens inside of a motor. The output from openMotor can be fed into OpenRocket to go all the way from propellant properties to altitude!

To answer your original question, yes, both openMotor and OpenRocket are safe and I use both all the time.

Thanks for clarifying things. I agree that both openMotor and OpenRocket are wonderful tools that I have installed.

ok so i downloaded JDK from this link:
i got the "macOS Compressed Archive"
so i downlaoded it and it is expanded and stuff, and when i open the openrocket it gives me the same message that i need a jdk. is there something else i have to do?
im not that good at computers
You do not need to install the JDK for OpenRocket if you use the link that timbucktoo provided above, and either way the one you just linked to will not work because the current version of OR requires JDK8.

Here's the link again: https://www.rocketryforum.com/threa...d-mac-to-solve-all-your-java-problems.143540/. Strongly urge you to use it.

There are many well-understood reasons but you don't need to worry about them. Enjoy! :)
