Under windows 10, the installer says invalid java jre.
I’ve got jdk installed and added to the system path (bin subfolder) and also set java_home (parent folder)
Java -version gives me
java version “1.8.0_92”
Java™ SE Runtime Environment (build 1.8.0_92-b14)
Java HotSpot™ 64-Bit Server VM (build 25.92-b14, mixed mode)
PATH variable has C:\Program Files\java\jdk1.8.0_92\bin\ in it.
JAVA_HOME variable is set to JAVA_HOME=C:\Program Files\java\jdk1.8.0_92\
Solved.
Turns out needed a later version of the jre.
A suitable error message would have saved me a lot of problems.
Java 8 (the last public version) should have worked, you may have had the 32 bit version of Java.
For others upgrading to a newer version may not work There are only a few that work the latest Java JDKs won’t be recognized as Java version.
By the way JAVA_HOME isn’t used by GWS.

It was 64 bit from the version print out above.
I think the installer requires 1.8 with subversion around 250 or so.
That could be it. I don’t see any of the older versions of JDK listed on the Oracle Download Site
My apology I did a classical response to an issue that was common not reading fully. It used to be a lot of people would install the x86 version of it and that is the 32 bit version and it confused a lot of people.

No worries.
My point being if you guys are still supporting the software, an appropriate message would be very useful and less frustration…most users don’t know anything about JRE and PATH etc.
Apparently that includes the tech writer that wrote the requirements. 
I’ll see if they can add something to the requirements.
Thanks for the nudge
