An error occurred while collecting items to be installed (Access is denied)

Question

If you have problems using the location: http://dl-ssl.google.com/android/eclipse/, try editing the location by replacing "http" with "https" or the other way round.

On Windows 7, the Program Files directory is protected so apps can't automatically write there. The simplest solution I've heard is just to install Eclipse into a user-writable location instead. For example, C:\Java\Eclipse

You should be able to just move your entire eclipse directory, there's no registry entries or anything else that ties Eclipse to the place where you extracted it.

[Edit] Have you checked that the directory it is complaining about i actually writable? Other than that, I really don't have any ideas. I haven't worked on Windows in several years and never with Win7. My only other suggestion is to just download the latest Eclipse, install it to a new location (do NOT intall it over top of your existing Eclipse), and point it to your existing workspace.

I just solved this problem by unchecking Read only checkbox of the Program Files/eclipse folder on win7.

Apply to all files and folders.

I had also the ADT Bundle that had the HTTP as update url. Changing it to HTTPS solved the problem for me.
