    Excellent, glad to hear it. The nice thing with the packaged installers is that they are not "installing Java on your PC". :)

    It's the installer linked in the first post of this thread. I think you already said it didn't work for you? (and BTW you should still upgrade at least to Windows 7 ;))

    THANKS SO MUCH, neil_w, for migrating Open Rocket to a Windows installer. I'd never had a problem with the Java version until I upgraded my Home Theater PC's display to a new Samsung 4K QLED last weekend. Open Rocket's apparently non-adjustable font scaling in the component tree was really ugly at the TV's native UHD resolution (3840x2160), with each line of text overlapping the next. But reinstalling Open Rocket with YOUR more Windows-friendly distribution fixed the issue perfectly.

    You're a hero!

    Good skies,

    I've downloaded OR then I found the .exe file here. I can do designs with nose cones, fins and rocket bodies but nothing else, no motors! Is it possible to use OR with W7?

    You are designating whatever tube you want to put the motor into as a motor mount, right?

    I've had similar with some of my older (read crappier) computers. The only way I've found to solve it is to run O.R on a better machine..O.S. does not seem to matter. And just for kicks, Windows 7 is no longer going to be supported..

    There are occasionally graphics driver issues that the packaged installers don't really have any influence over. Can you describe your system (hardware and OS)?

    I pretty sure there are known bugs in the 3D rendering screen. Not sure they are fixable.

    OH YEA! That is awesome. This has plagued my system for a long, long, time. Thank you for posting this fix.

    I discovered on my Windows 10 laptop that OR was still having issues. But then I ran across a post on TRF where a fellow was having the same issues I was having. He found that if he ran it in Windows 8.1 compatability mode that everything worked properly. So I did the same thing & it fixed the problems. :)

    I have struggled for two days trying to get OR to work, and then I found this sticky. Thank You so much, took 30 seconds and I'm up and running.

    I use win10, the Java OpenRocket has stopped launching. te .exeversion of OpenRocket gives simulation readings very high compared to the java version.. installed it on a friends computer, simulated and there was more than a 3000m apogee difference between them

    They should be identical. Can you post the ORK file?

    On my Win10 machine, EXE on left, JAVA on right:
    upload_2020-1-10_14-1-24.png

    All numbers identical (I could only do the commercial motor sims of course).

    Can you check that the simulation parameters are the same on both? Even then hard to imagine what could cause such large differences.

    I think that has happened to me in the past. In the edit simulation dialog, if you un-tick the "Use International Standard Atmosphere" box, the pressure sometimes defaults to a really low value. Could be that was the issue. Glad you figured it out, stuff like that can be maddening.

    For those using Linux, there are two solutions available:

    Code:
    $ /usr/lib/jvm/java-8-openjdk-amd64/bin/java -jar /usr/lib/openrocket/OpenRocket-15.03.jar
    
    That command line runs the OpenRocket .jar file using the Java 8 JDK instead of the Java 11 JDK.

    Alternately, go to https://www.rocketryforum.com/threads/openrocket-linux-appimage-beta-testers.155974/ and follow the instructions for downloading and running the Open Rocket AppImage. It's a single file that has everything you need to run Open Rocket without having to do anything else.

    Has anyone had an issue with the 3D images loading? I tried downloading Openrocket from the website as well as the link at the beginning of this post, but I can only get the basic side and end view. When I select the 3D view as well as the finished and unfinished view, the box is just blank.
