Error while installing Eclipse IDE
I could resolve the issue.
Delete all the files which are already on the system in users folder related to eclipse.
Delete workspace if any. (Save projects seperately)
Try installing the eclipse from the official site. Try not to go for the online installers. Install full software
The Software installation will be succesful
I came across an error code 1002 too as well. The problem appears to be caused by the online resource it is trying to contact. The solution resolved itself after waiting a couple hours. I post this because I was seeing similar complaints elsewhere and wanted to spread knowledge of this solution.
