Hi folks!
I’ve been a long time around reading posts of the community an using openfire as a public xmpp server. First on linux based machines, nowadays running windows server for smoother administration of all services 
However i have to set up a brand new (clean install) windows server system an get openfire up an running. I dont’ want to use the the “recommended” .exe-file because it comes with included JRE 32bit. I want to setup openfire using JDK or JRE 8 64-bit. But i’m running into some trouble here.
What i’ve done so far after installing windows:
Downloaded the Java SE Runtime Environment 8 Windows x64 .exe installer and run it. (jre-8u31-windows-x64.exe). So for me the necessary jvm is installed on that machine. Proofe here:
Now i’ve downloaded the latest openfire_3_9_3.zip (Does not include Java JRE) and unpacked it. If i try to fire up openfire using the openfire.exe in the /bin directory i get the error message saying that no JVM could be found on the system and that i have to define EXE4J_JAVA_HOME to a installed 32bit JDK or JRE.
Ok, first of all openfire didn’t recognise my installed JRE 1.8.0_31 at C:\Program Files\Java\jre1.8.0_31\bin\javaw.exe but it also claims it only will work with a 32bit version of java. So is this true?!
What i’ve tried further on:
Since i’m using the openfire_3_9_3.zip file, there is no “jre” folder within the openfire folder. So i created one and copied the contents of the downloaded jre1.8.0_31 in it. (I downloaded jre-8u31-windows-x64.tar.gz and unpacked it into the jre folder within openfire)
Next try firing up openfire.exe i get the error message, that the a JVM is found but it is damaged 
Tried the step with manually download the 64bit jre and copying it into the opfnire folder a few times but still get the same error.
Even using these hacked files to get openfire running with java x64 didn’t work out.
How to get openfire running under a windows x64 operating system using JRE or JDK 8 64-bit? For me, more guidance is needed here!
