Can't install Flex Builder 2 plugin in Eclipse 3.3/Europa

Question

[I hope Adobe reads these forums. I tried to submit this as a
customer service request, but the customer service request form
kept telling my I had to enter my First Name, Last Name, and Email
address, even though I _had_ entered them!]
I can't seem to install the Flex Builder 2 plugin in Eclipse
3.3/Europa. I had it installed fine in 3.2/Callisto. I uninstalled
it from there, installed Europa, then tried to install the plugin.
After I selected the Eclipse folder, I got the error:
"Please choose an existing Eclipse folder (3.1 or greater) to
be updated. This folder must contain eclipse.exe and the standard
folder named "configuration"."
All three conditions (3.1 or greater, eclipse.exe and
configuration) hold in my case, so I don't know what the real
problem is.

Answer 1

Actually it's quite simple. But you have to be warned. This
doesn't guarantee a bug free Eclipse setup and it isn't supported
by Adobe in any way. It is how-ever your only shot at getting
Eclipse with Flex Builder 2 AND php-development support, as Zend
has stopped deploying the php-development-requirement for Eclipse
3.2 (or at least I haven't found it in their archives.)
Flex Builder 2 simply checks for some files to see if the
directory you want to install to exist, so it recognizes the
directory as an Eclipse 3.1+ directory. Eclipse 3.3 however misses
the file startup.jar. If you simply copy startup.jar from an
Eclipse 3.2 directory into the 3.3 directory, Flex Builder 2 will
install in the 3.3 directory.
Again. This is not supported in any way by Adobe.

Kind regards.
PS. I would still like to have an Adobe Representative answer
the simple question: Is Adobe or is Adobe not working on getting
Flex Builder 2 to work on Eclipse 3.3? A simple yes or no will
suffice.
