Plugins not working in Eclipse on Windows 7 64-bit

Question

On my brand new Windows 7 machine, I downloaded Eclipse (Galileo) and several Eclipse plugins (Android's ADT plugin, Subclipse, etc.)

After rebooting, neither of these plugins are showing up in the IDE (nothing in the preferences, menus, etc.) but if I click "Installation Details" in the 'About Eclipse' popup, I see all of the plugins listed as Installed Software. (ex. Android DDMS 0.9.5, Subclipse 1.6.5, etc.)

How do I get my plugins to work?

Answer 1

I installed the following:

• jre-6u21-windows-x64.exe {you have to download it using IE-64bit} (C:\Program Files\Java\jre6)
• android-sdk_r06-windows.zip (C:\Program Files\Java\android-sdk-windows)
• eclipse-jee-helios-win32-x86_64.zip (C:\Program Files\Eclipse)

First time I tried, I had the same problem as above - no "Android SDK and AVD Manager" in Window menu, and no "Android" item in the Eclipse Window Preferences.

I uninstalled the ADT plugin and closed Eclipse. Then launched Eclipse in Administrator mode. Then I installed ADT, closed and reopened Eclipse as normal, and it worked :D

Answer 2

After mucking around for a while, I realized that when I copied the Eclipse directories to program files, I put them under the 64 bit directory, not the 32 bit (x86).. after moving eclipse to the new directory and reinstalling the plugin, it seems to work. Not sure if this is correlation or causation so maybe someone with more expertise can shed some light on this situation.
