if, your error is:

"Installer failed to initialize. File not found." or "Installer failed to initialize. This could be due to missing files."

first, rename OOBE Folder to OOBE.old.

to find OOBE:

64 bit win OS: Program Files x86\Common Files\Adobe\OOBE

32 bit win OS: Program Files \Common Files\Adobe\OOBE

mac os: HD>library>application support>adobe>caps

mac os: USER>library>application support>adobe>OOB

if that fails or isn't the exact error you see, uninstall, clean (http://www.adobe.com/support/contact/cscleanertool.html) and reinstall.

if you're using a dvd to install:

copy the disc contents to a desktop directory and install from that directory.

if you're using a mac:

1. Try to Create a new user account in Mac with Administrator Priviledges.

2. Login to the New user, Navigate to Mac HD> Application> Utilities> Adobe Installer folder, Locate products like Adobe Reader, Adobe Flash, Adobe Air and un-install them

3. Navigate to User Library> Application Support> Adobe and move Adobe to Trash.

4. Navigate to Mac HD> Library> Application Support> Adobe and move Adobe to Trash.

5. Start the installation again.
