Failed to install Android ADT

Question

I'm trying to install the ADT to Eclipse Indigo (32 bit). It consistently fails with the following message:

Cannot complete the install because one or more required items could not be found.

Software currently installed: Shared profile 1.0.0.1308118821836 (SharedProfile_epp.package.java 1.0.0.1308118821836)

Missing requirement: Shared profile 1.0.0.1308118821836 (SharedProfile_epp.package.java 1.0.0.1308118821836) requires 'org.maven.ide.eclipse [1.0.0.20110607-2117]' but it could not be found

I've tried reinstalling the ADT and the Android SDK, and Eclipse, without any luck. None of the other questions on this site seem relevant. I'm wondering if it's related to the migration of M2Eclipse from Sonotype to Eclipse, but I can't find anything.

EDIT:In order to explain why the answer accepted worked, I was installing on Windows 7 Home to an account that did have Admin permission and no password. However Win7 still prompts for the Admin password when you do something that needs Admin permission, even though the account has that permission and the password is empty. It seems that the ADT installation fails even under those circumstances. When I install to a non-Admin area it works.

Answer 1

Try running Eclipse as Super/Admin User, or move Eclipse installation somewhere with write permissions.

Answer 2

Technically this is an Eclipse bug, fixed in the next release. The central shared install needn't be writable to run eclipse (it should just install additional plugins into the user's cascaded configuration). See also: https://bugs.eclipse.org/bugs/show_bug.cgi?id=350645
