Hi Pedro,

If you haven't tried the latest weekly build (JavaFX 2.1b14) then I'd
suggest giving it a try. I had similar issues as you did and the cause
was related to a bug in JavaFX where old plug-in files were not being
updated when doing new installs. That bug has been fixed. I'd also
suggest closing all of your browser windows (and shutting down your
web browser) before installing the JavaFX 2.1b14 build. I also make it
a habit to do run the un-installer before doing a new install just to
be safe. When you are using beta or dev builds of any software it's
always a good idea to run the un-installer to remove old config files
and registry entries ... it's not a fix all ... I just find it to be a
good practice.

I agree that I'd like to see a nice installer that checks the
environment and resolves common issues. For my  purposes I'd love to
just be able to deploy a double clickable app and with a co-bundled
JVM so that I don't have to care about what the user has installed on
their system. What specific features or functionality do you think is
missing from the deployment technology in Java?
