This is the missing/corrupt files, in a self-extracting EXE.

Extract the 'AutoPlayDocs' folder, and everything you need is there.

Once you have extracted the 'AutoplayDocs' folder, run the 'fixed files' EXE.

Make sure you install to '{PATH_TO_EXTRACTED_DOCS_FOLDER}Adobe CS4payloads'

Overwrite all...

Once finished, follow these steps:

Extract files and HOWTO.txt from 'Internet.rar'

1. Run 'Disable Internet.bat' - Make sure you're offline!
2. Run keygen in 'keygen' folder for serial.
3. Run CS4 setup.
4. After install completes select 'Register Later'.
5. Exit CS4 setup.
6. Run Activation Disabler [ In Vista, right-click file and 'Run as Administrator' ].
7. Run 'Enable Internet.bat' - Make sure you're connected to update CS4!

I hope this fixes any problems - If not, I have the original DVD,
so I could just make a torrent of that...
