I\'m getting the error given below when I try to install the upgrade from Eclipse and it goes like half way and then throw the error.
An error occurred whil
Installig Eclispe ADT from market place solved this problem for me.
I had also the ADT Bundle that had the HTTP as update url. Changing it to HTTPS solved the problem for me.
If there are any proxy networks are configured remove them till plugins are installed
Changing from https:// to http:// worked for me
I solved the problem very easily.
Go to Control Panel -> Network and Sharing Center -> Windows Firewall -> Turn off Windows Firewall
And try to install again and see the magic :)
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.
