LXFree for Java uses a launcher application that searches for the appropriate JRE to use to run the LXFreeForJava.jar application. Its not uncommon for applications to have a problem finding the correct version of Java when you have more than one JRE installed. The minimum version of the JRE for the non-Java9 launcher is 1.7.0. That is why you see that message when the launcher can't find the JRE to use. It means it can't find the JRE, not that you specifically need version 1.7.0.
If you see the version 1.7.0 message after you have installed the Java 9 specific version, then it did not install correctly and you still have the 1.7/1.8 version. Open the control panel, choose 'Programs and Features' and uninstall LXFree for Java. Then, re-install the Java 9 version.
If the launcher still fails to find the JRE, you can test the ability to run LXFree for Java by opening a command prompt and typing:
java -jar 'C:Program Files (x86)LXSeries4WindowsLXFreeForJava.jar'
(This assumes Windows 10 64bit installed LXFree for Java into 'Program Files (x86)'. It is possible it is in the regular 'Program Files' folder instead. In that case, the command would be: java -jar 'C:Program FilesLXSeries4WindowsLXFreeForJava.jar')

LXFree allows you to draw light plots and generate the associated paperwork. LXFree integrates the design process by attaching data to objects in the drawing. This information can be edited through. If you’re not looking for a true visualization software, but instead a plotting software to map out your lighting, signal flow and DMX addresses, then maybe LXFree is for you. The purpose of this program is to plot out your lighting fixtures in a theatrical or live production environment.
