To determine the nature of the problem, I decided to launch Eclipse Europa J2EE with the new Flex 3 beta installed. As it turned out, I did not see the Flex Perspective that I would have expected. In fact, I looked around the menus and around the Eclipse Workspace, but the Flex Workspace or icons were not present anywhere!
Not here, in the menus...
And it was not available in the list of perspectives.
So. I suspected that Flex "core" was not installed at all (combining what I observed with the error message in the log file).
Upon further research via Google, I found a following bug entry that describes the scenario I encountered. The link is at http://bugs.adobe.com/jira/browse/FB-8206
It reads as follows:
Steps to reproduce:
1. Clean install of the Eclipse Europa J2EE version of Eclipse v3.3 directly from http://eclipse.org/
Eclipse was started, but not updated from any of the build sites. A default workspace is established and the various perspectives checked for function.
2. Un-installation of the Flash CS3 Flash player 9 was executed at this point.
3. Install of the Flex 3 Plugin was executed from filename: "flexbuilder3_b1_win_plugin_061107.exe" This action was repeated with uninstalling the plugin and the eclipse install to confirm it.
Actual Results: The Eclipse installation log is as follows:

I tried to register for the site, and received a confirmation e-mail, but I was unable to login at this point in writing.
update
Looking at the Add...Remove Programs listing in my Windows Vista Control Panel revealed that the OS had at least registered that the Flex 3 Builder Plug-In had installed. Uninstalling Flex Builder 3 caused another error to be displayed...
java.lang.Exception: There are no configured features with id com.adobe.flexbuilder.feature.core
...which basically meant that the plugin was not installed, so there was nothing to uninstall.
Additional searching showed that people had indeed installed Flex Bulder 3 beta on Eclipse Europa, just not the J2EE edition...
final update...
I finally got Flex Builder 3 beta to install on Eclipse Europa Classic 3.3.1 edition, and not the J2EE Edition. There were no problems during the installation, it just installed. So, I am concluding that the J2EE Edition Eclipse Europa currently will not install the Flex Builder 3 plug-in.
Next on my list, investigating the WTP (Web Tools Platform) option of Eclipse, and learn how it relates to Flex.
