Are you upgrading your Dragonfly Java App from an old version to a new version?

Please read the important instructions inside this page!

1 – Install the requirements

Install ALL the requirements from these links:

OpenJDK 11 (LTS)
Visual C++ redistributable 2019
Gstreamer MinGW Runtime. – during the installation process:
- select CUSTOM.
- click on “GStreamer 1.0” and choose “ENTIRE FEATURES WILL BE INSTALLED ON LOCAL DRIVE“.
- take note of the location where Gstreamer will be installed (e.g. C:\gstreamer\). You will need it later.

2 – Add Gstreamer to the environment variables

In Search, start typing “Environment Variables” and then
Click the Advanced system settings link.
Click Environment Variables.
In the section System Variables find the Path environment variable and select it. Click Edit. If the Path environment variable does not exist, click New.
In the Edit System Variable (or New System Variable) window, insert the path to the gstreamer executable. Assuming an installation of Gstreamer is inside C:\gstreamer\ then the path to add will have to be this:
- C:\gstreamer\1.0\mingw_x86_64\bin
Click OK. Close all remaining windows by clicking OK.

Dragonfly is a Java application and this means that there is no need to install it.
