That sounds like an issue with your JVM possibly. Check your path, to make sure the appropriate JVM is reachable.
You can also do a “java -version” at the command prompt.
I don’t know what the correct JVM is for 3.6, but I think if you’ve got the MS JVM it could cause problems like this.
If that doesn’t work, try launching the .exe from the command prompt - that way you should get to see any errors that are occurring.
Good luck.
