Eclipse Helios cannot access the specified device, path or file

I installed (downloaded) Eclipse开发者_如何学Go Helios (SR2-win32-x86_64). When I start eclipse.exe, I get the following error message window:

Windows cannot access the specified device, path, or file.  You may not have the appropriate permissions to access them.

This link: How to fix ""Windows cannot access the specified device, path, or file.." when rerun the program? is about a custom application, but it is the same message.

I changed the permissions of all the folders to write & read permissions. And I still get the error. I am running on Windows 7, 64-bit machine.

I run the program as administrator and get the same results.

Before installing eclipse, I downloaded and installed Java (jdk-6u25-nb-7_0-windows-ml.

Any ideas on how to fix this?

Edit 1:

The eclipse.exe file has *Allow Full control` permission for each user listed in the "Group or user names:" box.

This has been resolved. The company has a utility SOPHOS which was interfering with the installation of Eclipse.
