Popping the stack on this. In my testing, the 64-bit TurboVNC Viewer
package works just fine, with no modifications, when pointing JAVA_HOME
to a 64-bit JRE. Are you attempting to use the 32-bit TurboVNC Viewer
with a 64-bit JRE? If so, then that isn't supported. Because we use
JNI, the 32-bit TurboVNC Viewer package only works with 32-bit JREs, and
the 64-bit TurboVNC Viewer package only works with 64-bit JREs. You can
co-install 32-bit and 64-bit TurboVNC Viewer packages if necessary, and
invoke the vncviewer-java.bat script for whichever one matches the JRE
specified in JAVA_HOME, but I don't really understand why you can't just
use the 64-bit TurboVNC Viewer for everything.
