On Windows, the installer files are compressed and distributed as a zip file.
Use a zip utility to extract the installer files to a directory on your machine.
You can extract the installer files in the following ways:
Installation DVD. Copy the Informatica zip file from the installation DVD to a directory on your machine and then extract the installer files, or extract the installer files directly from the DVD to a directory on your machine.
FTP download. Download the Informatica installation zip file from the Informatica Electronic Software Download (END) site to a directory on your machine and extract the installer files.
