ROES now offers a native Windows installer package for Windows 10, 8, 7, Vista and XP (see note below for XP).
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.
