1) Unpack the Eclipse installation into the Program Files(x86)\eclipse folder.
2) Install from this repository: http://www.oaklandsoftware.com/updates/transform/ide 
3) The installation will complete successfully
---> However none of the plugins will be present.

Go to Help -> About -> Plugins and you will see no com.oaklandsw plugins.

If the Eclipse installation is located in another place, everything works.

I think this is happening because of the Windows Vista/7 thing of moving files that you write in protected areas to somewhere else and then they can't be found.

I have not tried this on Vista but expect it to be the same.

What Eclipse package are you using?  This might actually be an epp issue, but I'm not sure yet.

It's the jee package, so I think it's the issue you describe you in your email.

This bug still happens with Eclipse 3.7.

When installing Eclipse RCP based on Eclipse 3.7 into "C:\Program Files" users are unable to update the application unless UAC is disabled. 

We use the following class for updating our application:
http://dev.eclipse.org/viewcvs/viewvc.cgi/org.eclipse.equinox/p2/examples/org.eclipse.equinox.p2.examples.rcp.prestartupdate/src/org/eclipse/equinox/p2/examples/rcp/prestartupdate/P2Util.java?view=markup&revision=1.9&root=RT_Project

Update check always returns "nothing to update". After looking into server logs I realized that p2 doesn't send any requests even to retrieve content.jar/artifacts.jar! After disabling UAC the update worked as expected.

This bug was closed as a duplicate of another and the problem it refers to is not what you describe.  p2 can only update bundles it has permission to write to which is not the case with program files.
