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?

Solution 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

Solution 2

Moved the Eclipse to X86 and worked Thanks man that was getting annoying

Solution 3

I was getting this problem too. Installing Eclipse 64 bit into C:\Program Files\ and using a 64 bit JVM. For me the problem turned out to be the UAC (User Access Control). Once I turned this off via the control panel & restarted, I was able to install my plugins correctly.

No idea why Eclipse or Windows didn't prompt me in some way. Now to turn it back on after my plugins have installed.

Solution 4

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.

Do you see anything in the Error Log (Windows > Show View)? Are you using a 32bit or 64bit JVM?

Thanks very much for this - it was very useful. This is the key - unless you are running it in Administrator mode, the Eclipse installer isn't allowed to write the new plugin files into the Program Files directory. And apparently doesn't notice that it fails to do it, so it thinks it has completed successfully. The plugins aren't really installed unless you've run Eclipse in Administrator mode while installing - that's why they don't work.

Turning off UAC works, but is a little extreme - you can work around this by running Eclipse as Administrator while you're installing plugins.
