OpenRocket 2022 Pre-Installation Procedures

A few users have reported difficulties with installing new versions of OpenRocket, and some of these relate to pre-installation procedures. Before beginning the installation of OpenRocket, the following actions should be undertaken.

Close All Instances of OpenRocket

By default, all 2022 releases of OpenRocket install to the same location on your device; these releases even share preference and use files with version 15.03. Because of this, if OpenRocket is open when you attempt to install an updated release, the installation may not update all of the files needed for OpenRocket to function correctly.

Before installing an update, you MUST close all open instances of OpenRocket.

Uninstall Prior OpenRocket Releases

As described above, by default, all 2022 releases of OpenRocket install to the same location on your device. Although not expressly required, it is suggested that all previously installed 2022 OpenRocket releases be uninstalled before installing the updated release. This is not required, but is suggested to ensure the proper function of OpenRocket.

OpenRocket 2022 After-Installation Checks

Verify the Installed Release Number

A few users have reported that new installations of OpenRocket are not functioning correctly, only to find out that the wrong beta release was installed. After your installation is complete, and before doing anything else, verify that you actually installed the current release of OpenRocket by undertaking the following steps:

Step	What You Should See
1	If the release number shown in both images below is not OpenRocket Version 2022.02, then you have installed the wrong release of the OpenRocket. Uninstall that release, download the new release, and try again.

Check Settings

If everything looks good there, let's check settings.

Setting	What You Should Do
Off-screen Rendering	Some users have reported that the rocket shown in the design window is not full-size. This can occur if the off-screen rendering setting is not correct for your device. Using the Three-stage rocket example packaged with OpenRocket, this is what the problem looks like:
Too small
Correct size
Solution	In most instances, the solution is changing a setting in your preferences. You can find that setting here: Edit → Preferences → Graphics. And, you toggle the Use Off-screen Rendering setting. If it's off, then you turn it on. If it's on, then you turn it off. After changing this setting, you must exit and restart OpenRocket for the change to take effect.
	Experience has shown that those who use Apple Silicon Macs should uncheck this box, and those who use Windows should check this box. But, your OS platform may differ. If this does not correct the issue, contact development.
