Install iso file on Windows 7 with WinRAR

The Virtual CD application provided by Microsoft no longer supports Windows 7, so it cannot by used to install iso file. If you do not want to burn the iso file into a real DVD, or using third party application to mount  the iso file to a virtual driver, you can just unzipped the iso file using WinRAR, which is a well known safe application to install on Windows 7.

After it is unzipped, just start the setup file (setup.exe), it should work as if it is installed from a DVD. Certainly, this will not work if you need to boot the box from the iso file.
