It does seem like that. Perhaps it is finding an incorrect JAVA_HOME somehow to one already there?

[Mike Rathwell]

Hi @Doug kapell 

I think what may be breaking you is JDK 11. If you look at the supported platforms page for your version, it specifically says Oracle Java 1.8. Open JDK 8 and especially 11 comes MUCH later in Jira versions. 

Likely reverting to explicitly that will get you going.

[Doug kapell]

Thank you for the information. 

I have java 1.8.0_321 installed and am simply running the 7.4.14 windows installer. It seems the installer is attempting to use the wrong java version.
