Few days back - as the below post shows .. I’ve kicked Vista out of my machine and installed Windows 7 Ultimate 64 bit. Installation was very smooth on VAIO, the only driver I had to install manually was the one for the graphic device. (Here is the link on HOWTO install the graphics driver manually) You can install the 64 bit version of Java 1.6 directly from the Sun Homepage . Next point was then to install Eclipse 3.5, but for some reason the only have one common version for Windows at the Eclipse Download Page . But this fail as this was 32bit. so when back to the site to search for 64bit version of the Java EE Bundle. But :( , I couldn’t find one, then I went to http://download.eclipse.org/eclipse/downloads/ . There you can choose a 64 bit version, but that’s not the Java EE bundle. you can install this and will work fine !!! :) and then install the required dev plugins :) manually.
