OpenRocket: packaged installers for Windows and Mac to solve all your Java problems

neil_w · Nov 20, 2018

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

neil, what is the packaged version ? Could it maybe work on vista? Thanks.

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 )

David Schwantz · Nov 20, 2018

Understand, but never needed to before this!!!

David Schwantz · Nov 20, 2018

Hi neil, tried it again but still will not open. Thanks, but "oh" well. Dave.

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,
GlueckAuf

Glad it worked for you!

Mods, pretty please make this a sticky.

Background
Skip over this section if you just want to get up and running as quickly as possible.

Normally when you download and run a Java program such as OpenRocket, it executes using the system JRE (Java Runtime Environment) installed on your machine. Unfortunately, different JRE versions (especially the newest ones starting with 1.9) do not always retain 100% compatibility. Or even if they're compatible in theory, various problems can crop up that cause your Java program to misbehave or crash. There are other annoyances as well, like you can't pin the OpenRocket JAR file to the dock on the Mac (at least, not in the app area where you'd want it), and on Windows OR doesn't behave well with high-DPI screens.

A solution to all these problems is to use packaged versions of the application. These install like regular applications, and include their own JRE built in. This bundled JRE will remain completely separate from your system JRE, and will only be used by OR. Therefore you do not need to have Java installed on your machine. Over the course of several months, these packaged installers have resolved every single instance of user having trouble running OR. At least that I've heard about.

The current version of OR is (still) 15.03; these packaged installers run the original OR code; nothing has been changed or modified here.

Windows
Click here for the installer. The file is hosted on Dropbox, but you don't have to register or anything. If you see this dialog:

just click on "No thanks, continue to view" at the bottom and then click the "Download" button on the next screen.

The application uses a standard installer, but it doesn't (at present) provide a shortcut on the desktop or the start menu. After installing, the actual executable file for the application is installed into your user/AppData/Local/OpenRocket folder. So you can go in there, right click the "OpenRocket.exe" file, and create a shortcut, pin it to the taskbar and/or pin it in the start menu, whatever.

Mac
Click here for the .dmg file. Again, this is on Dropbox; see above instructions to bypass the "register" dialog if you get it. This behaves like a typical application image: double click the downloaded file, and it will open up a window showing the OR icon and an alias to the "Applications" folder. Drag the OR icon onto the Applications folder icon and the app is installed there. Then run it from that folder, or use Launchpad, Spotlight, or whatever other application launcher you favor.

Enjoy!

My God I"ve been trying to get OR to work for months, ow I found this thread and you installer worked!! Many Thanks

If this is not already,it should be a sticky. Fantastic job!!!!

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?

BEC · May 27, 2019

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..

I am still having problems viewing rockets in the 3D Rendering settings.

neil_w · May 28, 2019

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.

Thanks Neil Also, for all you Windows 7 people on this thread, it is still possible to download the most current Win 10 ISO, build a bootable USB drive with Rufus, and install Win 10 & activate it using your Win 7 key.
