Please download the installer here
The launch.msi installer file will download and the browser should prompt you to run it, please do so.
After it begins, as with any Windows installer, the User Account Control facility will darken the screen
and bring up a prompt to allow it to proceed (this may take several seconds depending on your system).
Depending on open Windows such as browsers, some of the download progress bars may appear behind these open applications.
During the install a desktop icon will be created for starting ROES in the future.
A guide to the install can be found here.
If this fails for any reason you may use the normal Java application by clicking here. If you do not presently have Java installed, please download and install it from the Java Download Page.
NOTE: Windows XP stopped receiving support and updates from Microsoft April 8, 2014 and is not considered secure any longer.

ROES Via Java Web Start
Any Apple system 10.7.3 or higher can launch ROES using installed Java Web Start. If you do not presently have Java installed, please download it from the Java Download Page.
To begin right-click/hold the Control key down and click here, choosing Download Linked File As… from the list that appears. In the dialog that opens at the top,
select either Documents (should appear as the default) or Downloads if desired and save the launch.jnlp file there.
Using Finder, open Documents (or Downloads) and right-click/Control-click on the launch.jnlp, then choose Open.
In macOS 10.8 and higher, a dialog will open to approve executing the file (doing so will start the ROES download and install).
A video of this startup procedure can be found here. Once this initial download and install occurs, you should receive a desktop icon to access ROES in the future.
OS X 10.6 is no longer supported due to Internet security requirements.
NOTE: You will receive a security message pop-up to trust the application to begin. Please click OK/Allow on these to allow the needed permissions for the program.
