Uninstaller encountered no JVM found problem
We encountered this problem (see below) for uninstaller when we removed java from the path
===========================================
No Java virtual machine could be found from your PATH
environment variable. You must install a VM prior to
running this program.
===========================================
We looked further and find the value of "lax.nl.current.vm=jre/jre/bin/java" in "Uninstall-FileNetQuickrServices-1.0.lax"
is incorrect. it should be
"lax.nl.current.vm=../jre/jre/bin/java"
Note the ../ here
the workaround is to include Java in the path. But We do bundle JVM when building our installer so this really should not be needed...
So is this a IA bug, a JVM bug,
or We forget to put some properties there?
This happened to many unix platforms like HP. I have not tested Windows and other platforms yet.
I appreciate your quick response...

Well, IA installers are Java-based, which means they need a JVM in order to properly operate. The same applies to uninstallers. Usually, IA is used for Java-based applications, which means a JVM is always installed, which will be used by the uninstaller. So in you case, you don't install a JVM, but this one is used only at install time, if you remove all JVM from the path, having this message when attempting to uninstall is normal, IA works as designed...

Well, we do bundle JVM in our installer. And installer works without external JVM. the issue is the config file generated by IA miss a "../" for java path. and then uninstaller could not find the JVM.
So not sure this is a IA bug, JVM bug?

This is only HP-specific, when the bundled jre is an JDK.
When using a JRE then uninstall works.
