The installer files are compressed and distributed as a zip file. The user that runs the installer must have read and write permissions on the installer files directory and execute permissions on install.bat.
You can extract the installer files in the following ways:
Installation DVD. Download 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. If you download the zip file to a directory on your machine, verify the length of the entire installation directory path, including the zip file name, is 60 characters or less.
FTP download. Download the Informatica installation zip file from the Informatica Electronic Software Download (ESD) site to a directory on your machine and then extract the installer files.
