Eclipse and Android Development Tools Issue

I attempted to install Eclipse and the ADT on my main computer at home and ran into a problem, I couldn’t get the Eclipse Plugins to install. I’ve installed this setup several times, on Windows XP, Windows 7 and Fedora 11 without any prior issues. My home computer is running Windows 7 x64. When I attempted to install the Plugins through Eclipse I got the following error:

Cannot complete the install because one or more required items could not be found.
Software being installed: Android Development Tools 0.9.3.v200909031112-12945 (com.android.ide.eclipse.adt.feature.group 0.9.3.v200909031112-12945)
Missing requirement: Android Development Tools 0.9.3.v200909031112-12945 (com.android.ide.eclipse.adt.feature.group 0.9.3.v200909031112-12945) requires 'org.eclipse.wst.sse.core 0.0.0' but it could not be found

I Googled the problem and got several results but none of the solutions resolved my problem. I then considered my other configurations and the difference in this instance. The main difference was that I had unzipped Eclipse into C:\Programs Files (x86)\. On the other machines I had unzipped Eclipse into C:\Programs where I tend to put applications which unzip rather than install through a Setup progam. Anyway this appeared to resolve the issue and the ADT successfully installed. I’m not sure if this issue is just related to x64 Windows 7 or whether it occurs with x86 or even Vista for that matter. Disabling the UAC may also have resolved the problem.
